Key specifications

Choosing the right option

Match the nut to the bolt, stud or rod: thread form, diameter and pitch must all agree. Sizes are nominal thread diameters in inches; compare the threads per inch with your bolt. Choose the class or grade to suit the bolt you are fastening, and confirm the pairing with your specification if the joint is load-critical.
