About this nut
This is a nut at strength class Grade A, supplied black, with an M3 thread. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.
A nut is the closing half of a bolted joint. Its property class is chosen to match the bolt it is paired with — a class 8 nut for a grade 8.8 bolt, so the thread strips before the bolt breaks. Used wherever a bolt or stud has to be tightened from the far side, and for locking and positioning duties on machinery and steelwork.
A coloured finish, in most cases a dyed passivate over a zinc layer or a dyed organic film. Appearance plus light corrosion protection.
M3 is a metric thread with an 3 mm nominal diameter and a coarse pitch of 0.5 mm (ISO 261). A standard hex head takes a 5.5 mm spanner across the flats.
There is no minimum order and no free-shipping threshold: buy one piece or a full container. Your order total is confirmed in the cart, before payment.
