Sirius 10.9 Grade Socket Button Head Screws BZP

The Sirius 10.9 Grade Socket Button Head Screws in BZP (Bright Zinc Plated) finish are high-tensile fasteners built for demanding mechanical and engineering applications. The low-profile domed button head sits flush and neat against surfaces, making these screws ideal where a clean, snag-free finish is required alongside serious holding strength.

Manufactured to grade 10.9 — a high-tensile standard — these screws deliver exceptional clamping force and resistance to shear stress. The BZP finish provides reliable corrosion resistance for general-purpose indoor and light industrial use. Driven by a hex socket (Allen key), they allow high torque to be applied precisely without the risk of cam-out.

Available in metric thread sizes from M3 to M12, with lengths ranging from 5mm to 75mm, there is a combination to suit a wide variety of assemblies and joints.
