M20‑2.50 × 100 mm Hex Cap Screw – Stainless Steel A4 (316), DIN 933

Engineered for long‑reach, heavy‑duty metric fastening in corrosive and high‑load environments, the M20‑2.50 × 100 mm hex cap screw is manufactured in accordance with DIN 933 standards from A4 (316) stainless steel. The fully threaded shank provides maximum thread engagement through thick or multi‑layer assemblies, ensuring consistent clamping force and reliable load transfer under demanding conditions. A standard hex head enables secure installation and removal using common industrial tools. A4 (316) stainless steel offers excellent resistance to rust, moisture, salt exposure, and chemical attack, making this fastener ideal for marine, outdoor, and industrial applications. Commonly used in heavy machinery, structural steel connections, equipment frames, and stainless steel fabrications where strength, corrosion resistance, and long service life are essential.
