To complete the part number, as detailed at
the bottom of the opposite page, you will
need to determine the following:
1. Shank Diameter: See performance
information on Introduction pages. Find
diameter code in the Dimensions table

2. Material: See performance information on
Introduction pages.
Quick Access Fasteners
3. Handle Style
4. Grip Length: This is the load bearing area
on the Lockwell® quick-release pin and is
measured from shoulder to the tangent
point where the ball intersects the shank
diameter.
Grip length for
Lockwell pins is
always specified in
thousandth-inch
increments, e.g.,
500 equals 1/2” grip
length.

2. Attaching links standard on all pins.
3. Double acting pins are available with a drive-out
feature. This feature is employed where removal of
pin is necessary while in a shear loaded condition. To
order drive-out, see part number example.
4. If greater “C” dimension is necessary add length
in thousandth of an inch after “F” letter. Example:
LG3CT300F750 (750 = .750 inch)
5. Pins are identified per AMS-STD-130 and applicable
specification.

quantity. Contact Southco customer service or
your local Southco Representative for pricing and
