Low-Strength Steel Thin Nylon-Insert Locknuts

These locknuts are about half the height of standard nylon-insert locknuts. Use them in light duty low-clearance applications or jam one against a hex nut to hold it in place. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use.
Zinc-plated steel locknuts resist corrosion in wet environments.
