M20‑2.50 × 65 mm Hex Cap Screw – Stainless Steel A4 (316), DIN 933

Designed for heavy‑duty metric fastening where increased grip length and superior corrosion resistance are required, the M20‑2.50 × 65 mm hex cap screw is manufactured to DIN 933 specifications from A4 (316) stainless steel. The fully threaded shank ensures maximum thread engagement and uniform clamping force in high‑load structural and mechanical assemblies. A standard hex head allows secure installation and removal using common industrial tools. A4 stainless steel provides 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.
