DIN 985 identifies the dimensional nut pattern. BS EN ISO 2320 is the reference standard for the functional properties of prevailing torque steel nuts. Please contact us before ordering to confirm compliance certification availability.
Match both the diameter and pitch to the bolt or stud. Fit the nut with the metal threaded end first and ensure the bolt passes fully through the nylon insert. Follow the tightening requirements for the assembly and check that the operating temperature is suitable for the nylon locking element.
