Jam thickness locknuts are about half the height of standard nylon-insert locknuts. Use in light duty low-clearance applications. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use. Max Operating Temperature of 250° F. Zinc Chromate finish provides protection against normal atmospheric corrosion.
