Sirius 10.9 Grade Socket Countersunk Screws BZP

The Sirius 10.9 Grade Socket Countersunk Screws BZP are premium high-tensile fasteners designed for engineering, manufacturing and industrial applications where a flush finish and exceptional fastening strength are required. Manufactured from Grade 10.9 high tensile steel with a Bright Zinc Plated (BZP) finish, these screws deliver outstanding mechanical performance with enhanced corrosion resistance for indoor and sheltered environments.

Featuring a precision 90° countersunk head, each screw sits flush with the surface after installation — ideal where a smooth finish is essential or where protruding fasteners could interfere with moving components. The hex socket drive enables high torque tightening while reducing the risk of cam-out. Available in sizes from M3 to M20 and lengths from 8mm to 100mm.
