About this nut
This is a nut in H59 Brass, at strength class H59, supplied self colour, 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 copper alloy: non-magnetic, electrically conductive and corrosion resistant in fresh water. Common in electrical, furniture and decorative hardware.
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.
Is this not quite the size or grade you need? Ask us — we produce small batches to drawing and to DIN, ISO, GB and JIS standards, and we consolidate pallet and container loads for trade orders.
