Quick Release Positive Locking Pins (Pip Pins)
These are cadmium plated 4130 alloy steel pins (180,000 psi tensile strength) and are manufactured to MS and NAS specifications. Two locking balls securely retain the pin unless the release button is depressed. The Length refers to the grip length (the distance from the shoulder to the locking balls).
Shear strength rating when mounted in double shear:
1/4" dia = 8200 lbs
5/16" dia = 12,800 lbs
3/8" dia = 18,400 lbs
Note: The locking balls are very low-profile and require a close-fitting hole diameter. We recommend using a matching AN960 Flat Washer (Part No. AN960, sold separately) on the ball side to ensure a precision hole size. If the hole is worn or chamfered, the locking balls could pull through.
