Industrial Nuts
Almost any time you are fastening parts together, a nut will be used to mate the parts. The nut that you require can depend on its thread characteristics.
The perfect nut for your application can depend on several factors including the material of the screw or bolt, weight of parts you are mating, the environment of structure, etc.
Our nuts can be customized to your application and industry. Please review all of our nut charts below and download the size charts
