How do spring nuts work?

Spring nuts utilise their spring-like design to grip onto bolts tightly and prevent the bolt from coming loose due to vibration or movement.

Can spring nuts be reused?

Yes, spring nuts can be removed and reused multiple times if they are still in good condition and have not been damaged.

How to install spring nuts?

Spring nuts can be easily installed using standard tools, such as pliers or a wrench. They can be inserted into pre-drilled holes in metal surfaces.

What types of threads are available for spring nuts?

Spring nuts are available in coarse and fine thread types to accommodate different types of bolts.

How do you select the right size of spring nut?

To select the right size of spring nut, first determine the size of the bolt you will be using and then the size of the pre-drilled hole in the metal surface.

Are there any special considerations when using spring nuts?

When using spring nuts, ensure that the pre-drilled hole in the metal surface is the correct size and that the spring nut is installed correctly to ensure a secure and reliable fastening.

Description

Spring nuts are suitable for securing screws and preventing them from loosening due to vibrations in ducting systems, cable management conduits & framing channels. Their spring-like design allows them to be easily inserted into a pre-drilled hole in a metal surface. Spring nuts are commonly used in construction and manufacturing applications. Raptor Supplies offers a wide array of Disco, Cooper B-Line and Anvil spring nuts featuring steel / stainless steel / mild steel / carbon steel construction for abrasion resistance.

Features

Spring nuts offer mounting points for panels where it is impossible to tap threads.
They attach to the panel surface with a clip and engage the male-threaded fastener either directly or through an integrated nut.
They are available in a variety of shapes to determine how and where to use them.
Selected models include multithreaded, tapped barrel u-nut clips that can be snapped into mounting holes and clipped onto panel edges to ensure a tight fit.
They are ideal for automotive and machinery applications, where vibration & movement need to be resisted.
