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. A thin nut is lower than a standard hex nut, so check the height your joint allows. 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.
