Socket Cap Head Self Colour Screws Grade 12.9 | Duchy Fasteners

These high-strength socket cap screws are engineered for demanding industrial and engineering applications where reliability and performance are critical. Manufactured to strict DIN 912 standards, they offer precise fit, consistent quality, and secure fastening in mechanical assemblies, machinery, plant maintenance, automotive projects, and construction environments.

Produced in premium high-tensile steel, including grades up to 12.9, these socket screws deliver exceptional load-bearing capacity and resistance to shear and fatigue, making them ideal for high-stress and safety‑critical joints. The zinc-plated finish provides excellent corrosion resistance, helping to protect against rust and wear in harsh working conditions while extending service life and reducing maintenance requirements.

Featuring a hexagon socket drive and cylindrical head design, these socket cap screws are perfect where high clamping forces are required and space is limited, allowing easy installation with standard hex keys or Allen tools. Their accurate threading and tight tolerances ensure smooth assembly, secure tightening, and long-lasting performance across a wide range of industrial and engineering uses.
