Sirius 10.9 Grade Socket Countersunk Screws M20 100mm Pack of 1

These high tensile countersunk socket screws deliver exceptional strength and a flush finish for demanding engineering and construction applications. Manufactured to ISO 10642 and DIN 7991 standards, the Grade 10.9 specification provides superior load-bearing capacity, making them ideal for securing heavy components where a smooth, low-profile surface is essential. The socket drive allows for reliable torque transfer and easy installation even in tight spaces, while the countersunk head sits completely flush with the workpiece to eliminate snagging and improve aesthetics.

- High tensile Grade 10.9 steel for maximum durability and resistance to shear and tension

- ISO metric thread M20 x 2.5 with a length of 100mm

- Countersunk head design for a flush, professional finish

- Internal hexagon socket drive for secure tightening with standard hex keys

- Manufactured to DIN 7991 and ISO 10642 specifications for consistent quality

- Black oxide or plain finish depending on stock (check listing for exact variant)

- Single screw per pack – ideal for replacement or small repair jobs

Trusted by engineers and tradespeople, these screws offer the reliability you need for structural fixings and high-stress assemblies.
