Sirius 10.9 Grade Socket Countersunk Screws M8 40mm Pack of 1

These high tensile countersunk screws deliver exceptional holding strength for professional-grade fastening applications where a flush finish is essential. Designed to sit completely level with the surface, they eliminate protruding heads and allow smooth assembly in confined spaces or where clearance is critical. Manufactured from premium alloy steel and heat-treated to Grade 10.9, they offer superior tensile strength and durability compared to standard stainless or mild steel fasteners, making them ideal for demanding engineering, automotive, and construction projects.

- High tensile Grade 10.9 for maximum load-bearing capacity and resistance to shear forces

- ISO metric countersunk socket head conforming to DIN 7991 and ISO 10642 for precise fit

- 40mm length with M8 thread suitable for medium-duty fastening in metal and plastic assemblies

- Hex socket drive allows secure torque application without cam-out

- Black oxide finish provides basic corrosion protection and a professional appearance

- Pack of 1 for targeted repairs or replacement of a single fastener

Choose these Sirius countersunk screws for reliable, low-profile fastening that stands up to heavy use.
