Hobson NH05VCM03 M3 Hex Nut, Class 5, Zinc Black Passivate

A hex nut is the standard six-sided nut. It is turned with a spanner or socket onto a bolt, stud or threaded rod of the same thread form, diameter and pitch. This page lists 5 Hobson metric hex nuts (metric thread, Class 5, zinc black passivate finish): M3 to M8.

The supplier names these nuts Class 5. The Hobson strength tables cover bolts, not nuts, so no strength figures are published for these nuts.

Pitch is the coarse pitch for each diameter from the Hobson thread table (manufacturer-stated). The supplier descriptions do not state a pitch.

The pack, box or bag quantity for each size is shown in the table.

Key specifications

Selecting 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.
