SS Allen Hex Socket Grub Screw:M8 x 20 - DIN 916/A2

This fastener is an Allen hex socket grub screw manufactured from A2 stainless steel, conforming to the DIN 916 standard for cylindrical solid headed machine screws. The M8 nominal diameter and 20 mm nominal length define its sizing for secure fastening tasks where a headless appearance or minimal protrusion is required. Buyers select this specific grade for environments demanding resistance to corrosion and rust, particularly where frequent cleaning or exposure to moisture is a concern. The A2 property class provides a reliable balance of mechanical strength and durability for general industrial and commercial applications. To choose the correct unit, ensure the M8 thread size matches the tapped hole and the 20 mm length allows sufficient engagement depth without interfering with internal components. The flat point or cup point design, inherent to DIN 916 grub screws, allows for precise clamping force against shafts or machined surfaces.
