How to Measure the Diameter of a Coiled Spring Pin
The outside diameter of a Coiled Pin is to be measured with a micrometer
from the seam (0º point) through the 90º point. Diameter is to be measured a
minimum of one pin diameter in length from the end of the pin.

Standard specifications apply except where otherwise specified.
All dimensions apply prior to plating.
Electroplated zinc is not available for pins greater than or equal to 8mm and .312" nominal diameter.
The standard finish for stainless steel pins is plain. Passivated pins are available at an additional cost.
Special sizes, duties, materials and finishes, including oil-free pins, are available upon request.
