Split Lock Washers

Offering minimal amount of vibration-resistant protection, split lock washers are made from a ring that is split at one point and bent into a helical shape, and when a screw is tightened, the washer is forced into a flat shape, and adds tension to the joint. Inch split lock washers meet ASME B18.21.1. Metric split lock washers meet DIN 127B specs.

Frequently Asked Questions on Split Lock Washers

Q: Do split lock washers work with heat treated fasteners (ex Grade 5 or 8.8)?

A: Yes, split lock washers can be reused if undamaged and spring back to their original shape.
