About This Product
These wedge lock washers are built to keep your bolts and nuts from backing out, even when things get shaky.

They're made from tough manganese steel, so they hold up under heavy loads and harsh conditions.

Each washer has an outer diameter of 16.
6mm, inner diameter of 10mm, and is 2.
6mm thick – that's the 3/8 size.
The clever dual-wedge design creates tension between the bolt head and nut, which locks everything in place and fights off loosening from vibration or dynamic forces.
Just slide one between your fastener and the surface, tighten it down, and the wedge action kicks in automatically.

You get 20 washers in the pack, plenty for machinery, construction, transportation gear, or any project where things rattle and shake.

Reliable and easy to use.
