Forged, heat-treated for abrasion-resistance and longer life. Designed for quick
change clamping which requires greater holding pressures than are available with
single cams. Mean clamping point pressure angle is from 3 1/2° to 4°, which makes
for stronger workholding.
Slip standard pipe over handle for more
leverage. Snug fit at handle collar and end.

Socket Shoulder Screws
Nylon Locking
• Material: 4140
• Thread: 2A-UNC
Socket Shoulder Screws are held to much closer tolerances than on standard Stripper
Bolts. The “B” dimension is always a plus to eliminate the binding on movable
plates. The “A” dimension is held closer for bearing-type locating. You’ll get more
positive holding power and greater turning leverage. Ideal for all sliding mechanisms.
Nylon locking element is incorporated in all Jergens Shoulder Screws.

Tru-Center™ Toggle Products
The Jergens patented “Tru-Center” products are the only pad type
on the market to provide true center line clamping. The cut-away
drawing illustrates how this works. The center line of the pad and
the center line of the nut always intersect at the point of contact
between the pad and the workpiece.
Adjustable Torque Toggle Screws
Perfect for delicate and fine clamping. Once the end
holding force is reached, the head breaks free.
Larger radius, straight knurled head for easy turning.

Toggle Pads
Carbide Tipped Toggle Pads provide multiple point
contact to compensate for surfaces that are rough or
out-of-round. Points will embed themselves in the
workpiece, which assures positive gripping. It eliminates
possible radial load on the workpiece.

Washers
Swing “C” Washer Assembly
The Swing “C” Washer has a concave
center for self-locating around the stud,
which prevents creeping while tightening, and allows acceptance of the mating spherical flange nuts. The Spherical
Flange Nut assures that the washer
cannot back out either during clamping or
due to vibration during the operation. The
shoulder screw has a nylon lock to prevent
loosening of the screw during operation.
• Material: Low Carbon Steel
• Heat Treat: Case Hardened
• Flange Nut and Shoulder Screw Provided

Washers
Self Aligning Washers (Two-Piece)
Upper
These washers are ideally suited for joining machine sections which are out
of parallel. They adjust themselves for a positive, firm base. With radius “E”
and the angular 140 combination, line contact is formed around the two mating
washer surfaces, allowing the two washers the ability to seek misalignment in
the companion clamping members. The heat treated I.D. of the bottom concave
piece is larger than the I.D. of the top convex section for free action. It is precision ground and the sharp edges are removed.

USAE™ Heavy Duty Flat Washers
USS + SAE = USAE
What is a USAE Washer?
• It is a simple but effective idea that is long overdue.
TM
• The Outside Diameter conforms to USS standards. This provides a washer
that is up to 36% larger than standard hardened washers.
More Contact Area = More Holding Power
• The Inside Diameter conforms to SAE standards. The small ID provides a
more precise fit on bolts, studs, etc.
• USAE Washers are also up to 37% thicker than standard hardened washers
for greater strength.
• Washers are made from mild steel. They are case hardened to 60 HRc and
have a black oxide finish.
• Bolt size is stamped on each washer for easy identification.

Replaceable Grippers
Tapered - Hardened Steel
Pointed Jergens introduces a new concept in replaceable grippers. It is now
easier to modify soft top jaws, strap clamps, or fixtures to hold irregularly shaped material. The grippers can be installed from one side,
using a combination center drill, a tap, and a box wrench. There is no
need to drill through holes from difficult to reach locations. Simply drill,
tap, and install.

Replaceable Grippers
The Jergens Replaceable Grippers are available in Hardened High Speed Tool
Steel or with Carbide Inserts. The points of the grippers embed themselves into
the work piece giving greater holding power with less actual pressure. Jergens
Grippers may be held in place using either a set screw on the flat of the gripper
or the threaded hole in the back of the gripper.
Use Jergens Grippers to make hardened serrated jaws from Jergens soft top
jaws or add the grippers to Jergens strap clamps for extra holding power. Use
Jergens replaceable grippers anywhere that rough surfaces are being held in
position for machining.

Adjustable Micro™ Clamps
Adjustable Micro Clamps decrease design and set-up times
for modular fixtures, work cubes, and standard fixtures.
Without changing hole locations, clamping range from
12mm to 35mm can be achieved.
The clamps are available with either smooth or serrated
faces which make them ideal for clamping machined parts,
castings, and rough cut stock. The clamps work with a cam
action, always following the contour of the workpiece for
maximum surface contact.
Measured from the centerline, each
face of these low profile clamps
increases 1mm (.0394) from the
smallest to the largest face.
• Cam action
• Low profile
• Available in four sizes
• Heat treated and plated
• Serrated or smooth edges
• Adjustable clamps and stops
• Includes Cam Screw

ID Expansion Clamp
The ID expansion clamp is the ideal way to hold parts on an inside diameter
for multiple machining on a vertical or horizontal machining center.
The larger diameter of the clamp is held to a close tolerance for precision
locating in a machined pocket on work cubes and fixture plates.
The customer machines the mild steel clamp to match the bore of the
part ensuring proper fit. Often times the clamps can be remachined
for different size jobs.
• Excellent for Palletized Setups
• Allows More Parts Per Workcube or Fixture Plate
• Tighten with Hex Key or Hydraulic Pull Cylinders
(Drill clearance hole for
longer bolt into hydraulic cylinder)
• Instructions included with each clamp
• Body Material: Mild Steel
• Low Profile
• Ideal for Secondary Operations
on Lathe Parts
• Easily Machined to Size on
Lathe or Mill

Micro™ Clamps
Jergens Micro Clamps feature both high hold down forces and low profiles, which
makes them ideal for building fixtures on Ball Lock fixturing plates. Two simple
components make them work: a hardened steel socket cap screw with an offset
head and a hexagonal washer. A half turn tightens or loosens the workpiece.
• Low profile makes computer programming easier
• Cam action provides fast, strong clamping
• Small size allows more parts per load
• Requires only a tapped hole in your fixture
• Available in stainless steel
• Note clockwise rotation recomended workpiece
stop should be on the right of the Clamp.

Micro™ Toe Clamps
This cam action fixture clamp provides positive down force while using
very little space on the fixture. Workpieces can be clamped in series
by using the back surface of a clamp to locate the next workpiece.
The hardened steel clamping element has both a smooth surface for
machined workpieces and a serrated clamping surface for rougher
work. The height of the clamp can be adjusted by milling the slot
deeper in the fixture plate.

To use the Jergens Modular Mini Vise: position the fixed
jaw clamp and tighten all three cap screws to secure
the clamp. Position the adjustable clamp and tighten
the outside capscrews. Insert the workpiece and tighten
the center cap screw. The adjustable jaw will force the
workpiece down against the base and over against the
fixed jaw clamp.
The Jergens Modular Mini Vise provides accurate
location and positive holding. The bases are
hardened and ground to the same height as
Jergens Rest Pads for accurate location. The jaws
are serrated and hardened to provide positive holding.
These versatile clamps may be used as shown, or the
jaws may be reversed to allow the workpiece to rest
on the machine table or fixture base. The clamps can
be made part of a dedicated fixture by removing the
T-nuts and fastening the 3/8-16” cap screws directly
to the fixture.
