M20‑2.50 × 200 mm Hex Cap Screw – Stainless Steel A4 (316), DIN 933

Designed for extra‑long, heavy‑duty metric fastening in corrosive and high‑load environments, the M20‑2.50 × 200 mm hex cap screw is manufactured to DIN 933 specifications from A4 (316) stainless steel. The fully threaded length ensures maximum thread engagement through thick or multi‑layer assemblies, providing consistent clamping force and reliable load transfer over extended fastening distances. A standard hex head allows secure installation and removal using conventional industrial hand or power tools. A4 (316) stainless steel offers outstanding resistance to rust, moisture, salt exposure, and aggressive chemical environments, making this fastener ideal for marine, offshore, outdoor, and heavy industrial applications. Commonly used in heavy machinery, structural steel connections, equipment frames, and stainless steel fabrications where extended length, corrosion resistance, and long service life are critical.
