Product Description

The term "cover nut" essentially describes a nut equipped with a protective covering, primarily intended to prevent moisture ingress and subsequent rusting of the nut.

Here are some common applications and purposes for using cover nuts:

Combating Vibrations: Cover nuts, when paired with stainless steel hexagonal slotted nuts and secured by a cotter pin, alongside screw bolts featuring holes, serve to endure vibrations and alternating loads. This arrangement effectively prevents the nut from loosening or coming off.

Insert Integration: The inclusion of an insert in the cover nut, which is tapped into the internal thread upon tightening the nut, acts as a deterrent against loosening. Additionally, this setup offers excellent elasticity to maintain a secure fit.

Wrench Card Feature: Cover nuts, when used in conjunction with hexagon nuts, possess a unique characteristic - the wrench card nut. This feature ensures minimal slippage during installation or disassembly. However, it necessitates specific tools like a single wrench, open-end wrench, or a dual-purpose wrench (open section). It is commonly employed in robust, straightforward components.

You'll often encounter cover nuts securing various components such as vehicle tires, lamp stands, and other similar fixtures. These nuts play a pivotal role in ensuring stability, preventing loosening, and preserving the integrity of mechanical assemblies.
