How to Choose the Best Diamond Grip Lock Washers
Material
Stainless Steel: Offers excellent corrosion resistance, making it ideal for outdoor or wet environments. It also provides good strength and durability.
Carbon Steel: Generally stronger than stainless steel and more cost-effective. It's often coated (e.g., zinc) to prevent rust, suitable for indoor applications.
Size and Fitment
Bolt/Screw Size: Lock washers are sized to match the bolt or screw they will be used with. Ensure the inner diameter of the washer is slightly larger than the bolt's shank diameter but smaller than the bolt's head.
Application Load: Consider the load the fastener will bear. Heavier loads may benefit from thicker, stronger washers.
Frequently Asked Questions
What is the primary function of a diamond grip lock washer?
A diamond grip lock washer is designed to prevent fasteners, such as nuts and bolts, from loosening. It achieves this by creating tension between the fastener head and the surface it's bearing against, counteracting vibrations and shocks.
How do I determine the correct size lock washer?
Lock washers are typically sized according to the bolt or screw they are intended for. You should match the washer's nominal size to the thread size of the bolt or screw. The inner diameter should be slightly larger than the bolt's shank.
Can I reuse diamond grip lock washers?
While it is generally possible to reuse lock washers, their effectiveness can diminish with each use. They may lose some of their spring tension after being compressed. For critical applications where fastener security is paramount, using new washers is often recommended.
What is the difference between a diamond grip lock washer and a split lock washer?
A diamond grip lock washer typically features raised teeth or a serrated pattern on its outer surface designed to bite into the fastener head and mating surface for enhanced grip. A split lock washer is a split ring that is forced into an elliptical shape, creating upward tension to resist loosening.
