Selecting the Correct Nut
Sizes refer to the nominal thread diameter, rather than the spanner size. Match both the diameter and UNC thread pitch to the bolt, screw or stud being used.
Select a compatible fastener grade and follow the tightening requirements for your assembly. Choose the required thread size and pack quantity using the product options.
