M20‑2.50 × 150 mm Hex Cap Screw – Stainless Steel A4 (316), DIN 933

Designed for very long‑reach, high‑strength metric fastening in corrosive and demanding environments, the M20‑2.50 × 150 mm hex cap screw is manufactured to DIN 933 specifications from A4 (316) stainless steel. The fully threaded length provides complete thread engagement through thick or multi‑layer assemblies, delivering stable clamping force and reliable load transfer over extended fastening distances. A standard hex head allows secure installation and removal using common industrial hand or power tools. A4 (316) stainless steel offers outstanding resistance to rust, moisture, salt exposure, and chemical attack, making this fastener ideal for marine, outdoor, and heavy industrial applications. Commonly used in heavy machinery, structural steel connections, offshore assemblies, equipment frames, and stainless steel fabrications where extended length, corrosion resistance, and long service life are critical.
