HEICO-LOCK Wedge Lock Washers 316 Stainless Steel - Large OD

HEICO-LOCK Wedge Lock Steel Washers are made of AISI 316L stainless steel. The wedge lock washers consist of a pair of washers with a wedge-locking action, which is a unique method that uses tension instead of friction to resist loosening under vibration. The key is the differences in angles. Angle “A” is large than angle “B,” so the pair of washers expand more than the corresponding pitch of the thread. HEICO-LOCK Wedge Lock Washers then positively lock the fastener in place, even in applications where extreme vibration or dynamic loads are an issue. Large O.D. washers are recommended for use on large or long holes, painted surfaces or soft materials like Aluminum. Made in Germany.
