Über diese Schraube

This is a screw in 40Cr Alloy Steel, at strength class Grade 12.9, supplied black oxide, with an 10# thread and a 1-3/4 in length. 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 screw threads directly into the parent material or into a nut, so the thread form, the point and the drive decide what it can be used for. Commonly used on machinery, tooling, appliances, electrical enclosures, furniture and automotive assemblies where the head has to sit low or be driven from one side only.

Grade 12.9 is the highest common commercial grade at 1220 MPa tensile / 1100 MPa yield, used for socket head screws and highly stressed joints. Specify Dacromet or black oxide, not electroplated zinc.

40Cr is a chromium-alloy quench-and-temper steel, the standard feedstock for grade 8.8 and above in China. It reaches 10.9 and 12.9 after heat treatment.

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.
