Sirius 12.9 Grade Socket Head Cap Screws M12 120mm Pack of 1

This single M12 x 120mm socket head cap screw delivers the exceptional strength and reliability required for high-stress fastening applications. Manufactured from premium alloy steel and heat-treated to grade 12.9, it offers a tensile strength of 1220 MPa, making it ideal for use in machinery, automotive assemblies, and structural fixings where safety and performance are paramount. The sleek black finish not only provides a professional appearance but also offers a degree of corrosion resistance. Designed with a fully threaded shank for lengths up to 40mm and a partial thread for this 120mm length, it ensures optimal grip where the thread is needed while leaving a smooth shank section for precise alignment and shear resistance. The internal hexagon socket drive enables secure and accurate tightening with the appropriate hex key, reducing the risk of cam-out or slippage.

- Manufactured to ISO 898-1 grade 12.9 for high tensile strength

- M12 thread size with 120mm overall length

- Fully threaded up to 40mm, partially threaded beyond for this length

- Black anti-corrosion finish

- Internal hexagon socket drive for positive torque transmission

- Suitable for use in demanding mechanical and engineering applications

- Single piece per pack for individual replacement or specific projects

A reliable choice for professional engineers and DIY enthusiasts alike.
