Low-Profile Cap Nuts

Low-profile cap nuts are about 20% shorter than standard cap nuts for use in low-profile applications.

Sanitary Low-Profile Cap Nuts

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.

High-Profile Cap Nuts

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

Sanitary Thread Caps

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

Cap Locknuts

18-8 Stainless Steel Distorted-Thread Cap Locknuts

An irregularly shaped thread grips the bolt for a stronger hold than nylon-insert cap locknuts. Made of 18-8 stainless steel, these cap locknuts have good chemical resistance.

18-8 Stainless Steel
Vibration-Resistant Cap Locknuts

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

Metric 18-8 Stainless Steel
Vibration-Resistant Cap Locknuts

To resist loosening from vibration, these metric locknuts have a nylon patch bonded to their threads that adds friction. They have good chemical resistance and may be mildly magnetic because they’re stainless steel.

Super-Corrosion-Resistant 316 Stainless
Steel Vibration-Resistant Cap Locknuts

With a nylon patch bonded to their threads for added friction, these nuts resist coming loose from vibration. They’re 316 stainless steel, so they have excellent resistance to chemicals and salt water.

Super-Corrosion-Resistant 316 Stainless
Steel Distorted-Thread Cap Locknuts

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.

Open-End Cap Nuts

The dome is open so these cap nuts can be used on bolts of any length.

Sealing Cap Nuts

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.

Cap Nut Assortments

Cap nuts cover and protect threads while providing a finished appearance.
