About this ISO 7380 screw
This is a screw made to ISO 7380, in SCM435 Alloy Steel, at strength class Grade 12.9, supplied black oxide (hardened), with an M16 thread and a 45 mm 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.
M16 is a metric thread with an 16 mm nominal diameter and a coarse pitch of 2 mm (ISO 261). A standard hex head takes a 24 mm spanner across the flats.
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.
Sold by the piece, so one is a valid order. Stock lines leave our warehouse within 24–48 hours of cleared payment, and freight is calculated at checkout from the packed weight and the destination.
