Nuts

Free-spinning Washer Nut

A type of nut that has a washer already attached to it. This allows the nut to turn freely during installation until the washer comes into contact with the surface, at which point further tightening will engage the locking mechanism. It's a one-piece solution that combines the functionality of a standard nut and a separate washer, simplifying assembly and potentially reducing the risk of omitting a washer during installation. 

Forged Eye Nut

A type of threaded fastener with a looped head, designed to create a secure lifting or attachment point. It's made by shaping metal, typically steel, using a forging process that involves hammering or pressing, which aligns and compresses the grain structure for enhanced strength and durability. These nuts are commonly used in rigging, securing equipment, and other applications requiring a strong, reliable connection. 

Hex Nut

A six-sided, internally threaded fastener used to secure bolts or screws. It's a common type of nut, often used in various applications due to its strength and ease of tightening with a wrench.

Caterpillar Hex Nut

A hexagonal nut (hex nut) used in Caterpillar (CAT) equipment.

Acorn Cap Nut

 A type of fastener that features a domed or rounded top, resembling an acorn's cap. It is designed to enclose the end of a threaded bolt or screw, offering both aesthetic and practical benefits. 

Coupling Nut

Internally threaded on both ends. Primarily used to create longer rod assemblies by connecting shorter pieces end-to-end. They can also be used to facilitate assembly of two fasteners or fittings with external threads.

Small Pattern Hex Nut

A type of hex nut with a smaller width across the flats and corners compared to standard hex nuts of the same thread size. This design makes them useful in applications where space is limited or where a smaller wrench is needed for tightening. 

Shaft Nuts

Internally threaded fasteners that used on shafts with an external thread. Shaft Nuts are used to hold bearing assemblies in place around a round shaft. Metric shaft nuts can also be used to secure components such as gears or pulleys onto a shaft.

Hex Jam Nut

A type of fastener that is similar to a standard hex nut but thinner, typically half the height. It is often used to "jam" or lock another nut in place, preventing it from loosening due to vibration or rotation. They are also used when a lower profile nut is needed. 

Left-handed Nut

 Also known as a reverse-thread nut, is a type of fastener with threads that tighten when turned counterclockwise, opposite to standard (right-handed) nuts. This design is used in applications where a standard nut might loosen due to rotation or vibration. 

Nylon Insert Nut

A type of lock nut that uses a nylon ring or collar to prevent loosening due to vibration. The nylon insert, with an inner diameter slightly smaller than the bolt's threads, deforms elastically when installed, creating friction that secures the nut and resists loosening. These nuts are commonly used in applications where vibrations are present and a secure, frictional fit is needed. 

Flange Nut

A type of nut that has a wide flange or collar on one end. This flange acts like a built-in washer, spreading the pressure of the nut over a larger area, which helps prevent damage to the material being fastened and reduces the chance of loosening due to vibration.
