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 the nominal thread diameter in millimetres; compare the pitch 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.
