M20‑2.50 × 70 mm Hex Cap Screw – Stainless Steel A4 (316), DIN 933

Designed for heavy‑duty metric fastening where extended grip length, strength, and corrosion resistance are required, the M20‑2.50 × 70 mm hex cap screw is manufactured to DIN 933 specifications from A4 (316) stainless steel. The fully threaded shank provides maximum thread engagement through thick or multi‑layer assemblies, delivering consistent clamping force and secure load transfer under high stress. A standard hex head enables reliable installation and removal using common industrial tools. A4 stainless steel offers excellent resistance to rust, moisture, salt exposure, and chemical attack, making this fastener ideal for marine, outdoor, and industrial environments. Commonly used in heavy machinery, structural steel connections, equipment frames, and stainless steel fabrications where durability, strength, and long service life are essential.
