More durable than plastic caps, these provide the most protection from abrasion and impact.

These metric cap nuts have good chemical resistance and may be mildly magnetic.

These cap nuts have excellent resistance to chemicals and salt water.

Certified by EHEDG (European Hygienic Engineering and Design Group) to meet sanitary design standards, these cap nuts fit into tight spaces to cover and seal exposed threads in your food processing facility.

Cover exposed threads with these caps to help prevent bacteria growth in food processing areas and other sanitary environments.

These cap nuts offer at least three-times the thread depth of standard cap nuts and are about twice the height.

A nylon patch bonded to the threads of these reusable nuts adds friction to prevent loosening under vibration.

With an irregularly shaped thread, these locknuts grip the bolt for a stronger hold than nylon-insert cap nuts and resist loosening from vibration. They’re made from 316 stainless steel, so they have excellent resistance to chemicals and salt water.

A silicone seal prevents leaks and seals contaminants. Also known as acorn nuts, these cap nuts have a smooth rounded head that covers and protects threads while creating a finished appearance.
