Internal-Tooth Lock Washers for Soft Material
Slightly domed with an oversized outside diameter, these washers distribute your fastener's load over a larger surface area than other internal-tooth lock washers to limit damage to soft material. Internal teeth dig into the screw head to prevent joints from loosening under vibration. Washers are zinc-plated steel for corrosion resistance in wet environments.
