Raptor Supplies offers a wide range of acorn nuts from brands like B&P Manufacturing, Micro Plastics, Gorlitz, Vulcan Hart & CS Johnson. Acorn nuts also make the bolt or stud ends look clean & attractive, and improve safety on selected joints & sensitive applications.

Buying Guide
Based On Body Shape / Profile
Standard
Standard sized acorn nuts are used for general fastening applications.

These extra-wide high profile acorn nuts have greater width & height than standard acorn nuts. They have high side surfaces to provide a large gripping area for a wrench.
Low
Low-profile acorn nuts are shorter in height than standard acorn nuts.
High
High-profile acorn nuts provide greater thread depth than standard acorn nuts, owing to their greater height.
Open End
Open dome acorn nuts can be used on bolts or rods of any length.
Based on Finish / Coating
Black Ultra-Corrosion-Resistant Coating
Provides greater corrosion resistance than zinc plating; ideal for materials exposed to chemicals
They prevent loosening of nuts due to vibration. Even though these nuts are reusable, the holding power of nylon inserts decreases with each installation / removal.
Distorted Thread
Also known as acorn locknuts or distorted thread cap nuts, these nuts have irregularly shaped threads that provide a stronger hold over bolts than nylon-insert acorn locknuts.
