Optia Wedgelock – Shake-Proof Locking You Can Trust

Tired of bolts working loose under vibration? The Optia® Wedgelock system is your go-to vibration-resistant fastener designed to keep joints secure under extreme dynamic loads. Whether you're in construction, rail, automotive, or heavy machinery, Wedgelock prevents loosening where traditional bolts fail.

This clever two-part wedge-locking system uses specially designed serrated washers that interlock during tightening. When subjected to vibration, the wedges create a tension-locking force that keeps the bolt tight — no matter how rough the ride gets.
