Sirius 10.9 Grade Socket Countersunk Screws M8 20mm Pack of 1

Engineered for demanding fastening applications where strength and a flush finish are critical, these M8 x 20mm countersunk screws deliver exceptional holding power while sitting completely level with the surface. Their high tensile grade ensures reliable performance in structural assemblies, machinery, and automotive work where standard screws would fail under heavy loads. Each screw is precision manufactured to ISO 10642 and DIN 7991 specifications, guaranteeing consistent dimensions and compatibility with standard hex keys.

- Manufactured from high-grade alloy steel with a tensile strength of 10.9 for superior load-bearing capacity

- ISO metric countersunk socket head design allows a smooth, flush finish in countersunk holes

- Complies with DIN 7991 and ISO 10642 for interchangeability and dimensional accuracy

- Pack of one screw, ideal for replacements or single-point repairs

- Blackened surface finish provides basic corrosion resistance in dry indoor environments

- Hexagon socket drive enables high torque application without cam-out

- 20mm length suits medium-thickness material clamping and recessed installations

Perfect for professional engineers and serious DIY users who demand precision and strength.
