Hi Collar Split Lock Washer, Hillman, Chrome, #8

An assortment of chrome-plated hi-collar and split lock washer variants from The Hillman Group. Ideal for situations where potential loosening from corrosion or vibration is a concern, split lock washers are used to prevent nuts and bolts from coming loose. These fasteners contain split ends that help inlock in into the mating material, thus providing a locking feature when tightened beneath a nut. Hi-collar lock washers are thicker than standard split lock washers. This provides stronger holding power.

• Split ends grip the material surface to prevent loosening during vibration
• Made of high-strength steel
