Product Description

A Cap Nut protects bolt threads underneath it, whilst providing a cleaner, more aesthetically

pleasing appearance and improving safety on some applications.
If an application requires a smooth finish or exposed threads to be covered, cap nuts are an

excellent solution for this - and they come in a number of styles including low crown and acorn

nuts. Available in a wide range of materials, from stainless steel to brass and everything in

between, and can be polished for a shining, aesthetically pleasing appearance. They can be

created with both coarse and fine threads but this will create differences in price.

The Acorn Center Lock Nut machined from bar or if volumes and size allow, can be cold formed.

Acorn locknuts are produced by installing 2 deflections in opposite flats precisely in the center the

nut hex. Low Profile Acorn locknuts are not required to meet the thread start or torque requirements

of Full Hex Center locknuts.

 

 

Applications

The Acorn locknut is used for either decorative purposes and/or to protect from scratches

when surfaces would otherwise encounter exposed screw threads. Acorn Center locknuts are

typically found in Furniture, Medical and Recreational Vehicle Assemblies. Mating parts must

extend at least one thread past the locking element to assure locking element engagement.
