Flat Washer Facts From WCL
BULLETIN
Materials & Shapes
Washers are made from virtually
any metallic or non-metallic
material that can be stamped;
including low and high carbon
steels, steel alloys, copper,
phosphor bronze, titanium,
aluminum, fibre, mica, mylar,
rubber, nylon, teflon, phenolic
and many more. I.D. and O.D.
can be configured to provide
any size and shape required.
They can be round, square,
rectangular, hexagonal, oval, or
non-symmetrical. They can also
have tabs, crowns, notches, and
may be countersunk in a variety
of degrees.
Hardness
Wherever possible, specify
commercial quality, low carbon
steel. This generally meets
most application needs in the
most economical manner. Only
specify tempered material if
special hardness is critical to
the application. Tempers such
as 1/4 or 3/4 hard in steel are
more difficult to obtain and,
therefore, more costly.

Plating
If it is necessary that a part be
finished by the application of a
coating such as cadmium, zinc,
nickel, anodize, silver or gold,
the correct required finish
should be clearly defined to
avoid unnecessary expense. If
commercial plating thickness is
acceptable, it should be so
noted. If a special thickness or
a post finish is required, it
should be clearly described
and specified as such.

Ordering Quantities
There is an inverse relationship
between quantity and price: the
larger the production quantity, the
lower the unit price. For economy,
order the largest quantity possible.
WCL may then schedule economical
shipments of your parts in increments based on your anticipated
needs and usage, rather than making
a single delivery.
GENERAL INFORMATION & REFERENCE SPECIFICATIONS
FLAT WASHER AVAILABILITY - The flat washers listed in this catalog represent only a small portion of the many that
are available. The WCL inventory contains over 7000 different sizes, in different materials, etc. All of these cannot be
listed here because of space limitations. Source tooling is available for many others not shown. Pages 29 and 30 show
some of the more commonly used specials that are available, cross-referenced to appropriate ordnance numbers.
QUALITY ASSURANCE - WCL has a Quality Assurance Department and Program to confirm the integrity of all the
products it sells. We represent only those manufacturers that have an outstanding reputation for consistently providing
high quality parts, and we maintain complete procurement data and certifications from our suppliers and processors on
pertinent Stock Reference items.
SPECIFICATIONS, TESTING AND CERTIFICATIONS - A detailed explanation of the test requirements called for under
the various military specifications and a listing of the many certifications available through WCL, appear on pages 8 and
9. WCL can be an indispensable source for parts conforming to all MIL-SPEC requirements. If parts are not tested to
MIL-SPEC requirements, they are not MIL-SPEC parts. If parts are not plated to MIL-SPEC requirements, they are not
MIL-SPEC parts.
NOMINAL DIMENSIONS - Nominal dimensions are provided on all flat washers and are so identified. They are
provided for reference only. Parts are produced to standard commercial tolerance and are appropriate for all
commercial applications. With regards to thickness dimensions indicated, parts conform to stamping industry standards.
WCL frequently stocks popular washer sizes in more than one thickness and this is indicated in the charts. For specific
tolerances and thicknesses on other referenced parts, please contact WCL. Parts with special tolerances and thicknesses can be provided as specified.
INSIDE DIAMETER PROFILE - The inside diameter of a conventional flat washer traditionally has three distinct profiles
as a result of the punch press process. As the punch enters, there is some pushing in of the material which results in a
rounded corner section (A). Then, as the punch
O.D.
advances, it creates a substantially parallel section until it
Punch entry side
I.D.
approaches the exit point and a tapered breakout occurs
A
(B). Dimensions given for inside diameters, and their
Thick
B
accepted tolerances, apply to the parallel sections. At the
break out side of the washer, the specified maximum
Punch exit side
Figure 1 - Washer Profile
inside diameter may be exceeded by a maximum of 25%
(Exaggerated for clarity)
of the specified thickness. (See figure 1.)
MATERIALS AND PLATING - The charts on the following pages show the availability of washers in the more popular
materials. Many of these washers are available in other non-ferrous materials and non-metallics. In the appropriate
materials availability columns, standard dash reference numbers are used for AN, MS and NAS parts as well as for some
commercial parts to indicate the availability of these parts in the designated materials and finishes. For commercial
parts, an “X” designation is used. (See figure 2.)
METRIC WASHERS - The many metric flat washers available from WCL are designated with an (M-) prefix for the
metric screw or bolt size in the “Size” column. Metric washers are available in either DIN or ANSI/ASME B18.22M
specifications and the relevant specification is indicated in the particular “Reference”column. (Example of M6 see Figure
2.) Material thicknesses on metric parts generally conform to conventional U.S. washer manufacturing tolerances unless
the parts have been stamped from material produced to metric thickness.

“AVAILABLE” - This designates standard commercial parts in the predominant dimensions shown and in the materials
designated by an “X” in the appropriate columns. Call for availability.
REFERENCE PART NUMBERS - Washers listed in the charts on the following pages are referenced to appropriate
commercial and government part numbers. The following observations on these particular references may be of help.
AMERICAN NATIONAL STANDARD WASHERS - Designated by ASME B18.22.1, these washers are of two types:A and
B. Many washers are available in either narrow (-N), regular (-R), or wide (-W) series.
AN 960 - Most AN960 steel washers now in stock are made to Revision 21, which specifies steel to MIL-S-7952. Some
remaining stock is made to Revision 18, which may still be used in accordance with the government’s “phase-in,
phase-out” policy on most specification revisions. The entire 960 series will eventually be replaced by the NAS 1149
specification, which is now recommended for use in new designs. AN960 washers are stocked, in accordance with the
specification, with CAD II plating. AN960 washers are also stocked in other materials and platings, including : Stainless
Steel, passivated (-C) and black oxide (-XC); Brass (-B);Aluminum, plain (-D);Aluminum with a Chemical Film (-JD); and
Aluminum Anodized (-KD).
AN 961 - washers, having the same dimensions as the AN960 washers, appear in the Brass column and are available with
either a Tin (-T or a Silver (-S) finish. Note the AN letters are not in the column and are designated by “961-1016.” (See
Figure 3 Brass Plated column.)
AN 970 - washers have oversized outside diameters and are stocked in Steel, plated Cad II (yellow) or, commercially, with
a zinc finish. (See Figure 3 for example in Steel and Stainless,AN 970-10 & -C10).
Page 6
NAS 620 - washers are used to mount small items with vent radii and other interferences, most commonly found in
electronic components. Stocked in steel, stainless steel, brass and aluminum.
NAS 1149 - this new specification was introduced in 1992 to eventually replace the AN960 specification which is now
classified, per revision 21, as “inactive for new design.” This means that on all new products NAS1149 washers may be
specified. AN960 washers may continue to be ordered and used in the ongoing production or repair of already designed
products. NAS1149 duplicates most of the AN960 parts, but additional, material options permit specification of Titanium
and other special high strength alloy materials. Selected NAS1149 parts are referenced in the following charts as an
indication of the availability of this series. WCL stocks many of these washers and can supply detailed information and
prints when requested. Boeing is one particular used who requires this series. (See Figure 3).

materials are available, as well as conventional plated steel. Not specifically listed, but also available from stock are
Copper (-500 series) and Nickel Copper alloy (-400 series). The NASM series supercedes the MS15795, but the part
numbers remain the same.
MS 27183 - specifies general purpose washers in Steel, grades 1008 through 1020 ASTM-A109, #4 temper with Cadmium
II plating. This series is also available commercially with zinc and other finishes. MS27183 supersedes MS 15795-200
series.
MS 51496 - these Army and Air Force customer numbers have a reduced outside diameter (narrow series) and are made
from Stainless Steel, 20 HRC minimum, passivated, with a 2.0 magnetic permeability or less. This specification may be
subject to modification by the Committee on MIL Specifications as a result of difficulties experienced in meeting some
dimensional, material and hardness requirements.
MS 9321 and MS 9549 - made from AMS 5510 stainless steel in a variety of sizes.
MS 14151 - washers are made from Stainless Type 304 and are normally used in electrical and other non-corrosive
applications.
MS 16212 - specifies a medium series washer made from non-magnetic Stainless having minimum tensile strength of
50,000 psi.
N 400, N 401, N 402 - this series of washers are General Electric reference numbers for flat washers. Many of these G.E.
part numbers cross over to MS series, but have tighter tolerances. WCL supplies MS series to G.E.‘s tighter tolerances.
OTHER REFERENCED PART NUMBERS - washers meeting other specific OEM references are also shown. These include
Martin Marietta, Boeing, Ordnance, etc. WCL offers many other Mil Spec parts, see High Strength-Heat Treated and NonMetallic sections for numbers that fall under these categories.

TORQUE WASHER LINE
A complete line of unique square-holed Torque Washers is
now available from WCL Company.
The square-holed washer is designed for use with a carriage
bolt. Four bent prongs on the washer can be embedded in
wood, plywood and other ductile materials, making the washer
self-retaining during assembly. The finished square hole in the
washer mates with the square shoulder on the carriage bolt. As
the washer is fixed in place, the square shouldered bolt is
prevented from rotating. The washer also provides a smooth
bearing surface and distributes the fastening load, preventing
embedment in the soft material and the splitting and loss of
holding power that can result.
WCL stocks Torque Washers with square inside diameters of
1/4", 5/16" and 3/8" in a 1" O.D. and a 1/2" square hole washer
with a 1-3/4" O.D. Also available soon are 5/8" and 3/4" square
hole with a 1-3/4" O.D.

THERMOPLASTIC - NYLON FLAT WASHERS AND SPACERS

resistance to abrasion, repeated impacts, organic solvents,
oils, gasoline and temperature extremes. It has good creep resistance (yielding to pressure) and ability to self-extinguish. NYLON
6/6 is commonly used as punching grade stock and NYLATRON

POLYPROPYLENE is one of the most economical and popular
forms of plastic used for flat washers today. Material characteristics include chemical resistance, living hinge, light weight, arc
resistance, good dielectric strength and a flammability grade. Four
grades are used; the General Purpose Grade has a UL #E31765A.
The High Temperature Grade uses additives to sustain rigidity
under high temperature condition. FR Grade is a flame retardant
polypropylene with a UL rating of SE-0 (1/8" thick).
MYLAR® POLYESTER FILM - EL and A series - Washers made
from this material are used in such applications as: carriers in
microfilm, magnetic tape, carbon ribbons and metallic yarn;
electrical barriers for capacitors, motors, membrane switches and
wire and cable; and as thermal barriers in wire and cable tapes.

THERMOPLASTICS - TEFLON FLAT WASHERS
VIRGIN TEFLON, due to the molecular structure of its resin, is
almost universally inert. Washers made from this material are
impermeable to most corrosive liquids, vapors and gasses, even at
elevated temperatures or when under pressure or in a vacuum.

The material also has excellent electrical and dielectric properties. A tendency to creep or cold flow under compressive load,
limits the use of these washers in mechanical applications.
