Wire Locking Capscrews Wire locking of capscrews is used when maximum lock assurance is required when periodic visual inspection is not possible. The illustrations below show the recommended wire locking methods for various right hand thread capscrew patterns. For patterns not shown, wire lock the screws “in pairs”. For odd numbered patterns, wire lock the screws in pairs except the remaining 3 capscrews wire lock together
Patterns for Wirelocking Capscrews
Use 14 gauge soft annealed lock wire. Thread the wire through the capscrew head so that tightening stress on the wire will exert a tightening torque on the direction of capscrew thread. (The illustrations show lock wire threading for right hand threaded capscrews. Reverse the lock wire patterns shown for left hand capscrews.)
