About this tool
This is a tool in Carbon Steel, supplied blue, 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 fitting, driving or measuring tool matched to the fastener sizes we stock, so the drive and the head are known to fit before you buy. Used for installation and inspection work, and for checking thread and dimension before an order goes into production.
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.
A coloured finish, in most cases a dyed passivate over a zinc layer or a dyed organic film. Appearance plus light corrosion protection.
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.
