5/8″/M16 316 Stainless Steel Heico Lock Bolt Securing Lock Washer – NEW 100/Pack


Wedge-Lock washers are a paradigm shift in fastening technology relying on the physics of tension instead of friction to maintain clamp load. The washer system is highly resistant to constant vibration, high dynamic loads and thermal cycling. The matched set of washers are used in applications where life safety and equipment reliability are paramount.

1. Tension based design – Clamp load is maintained by utilized tension in the bolt; highly resistant to constant vibration, high dynamic loads and thermal cycling

2. Unidirectional serrations – No damage to painted surfaces

3. Optional larger outer diameter – Suitable for slotted holes and soft metals

4. Wedge-Lock design – Effective at very low preloads; effective with short bolts

5. Delta Protekt® Zinc Flake Coating – High corrosion resistance

6. Through hardened carbon steel version – Suitable for high tensile 12.9 bolts

7. Surface hardened 316 stainless version – Good corrosion resistance

8. Two piece cam design – Reusable; eliminates nylon insert nuts, metal lock nuts, double nuts, adhesives, safety wiring, friction based lock washers; low off torque force

9. Washer halves glued together – Convenience of assembly
