About this tool
This is a tool in Iron, supplied black oxide, 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 iron grade in our catalogue. Ask us for the mill certificate and the exact mechanical properties of any line before you specify it into a design.
This line ships worldwide from our own warehouse. Express courier, air parcel and postal services are all offered at checkout, with a tracking number e-mailed as soon as the parcel is handed over.
