About this tool
This is a tool in S2 Tool Steel, supplied red oxide, with an 5.0mm 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.
A s2 tool steel 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.
An oxide conversion coating, roughly 1–2 µm, normally oiled. It keeps dimensions exact and adds mild corrosion resistance.
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.
