Product application

Metal nuts and hex nuts are securing fasteners that are designed to be mated with a bolt with a similar threading pattern. Hex nut products function through a temporary joint holding structure that is created between the nut and bolt when matched. Nut bolt fastening products can be used for a wide range of applications and are offered in many unique sizes and shapes.

 

 

How to Install a Hex Nut

Since six-sided hex nuts are now the basic standard shaped nut in the industry, a wrench, socket or driver tool can be easily used to tighten or loosen hex nuts that requires a tool. Other types of nuts, such as a knurled nut or wing nut can be tightened or loosened by hand, which in certain applications is extremely useful.
