M20‑2.50 × 140 mm Hex Cap Screw – Stainless Steel A4 (316), DIN 933

Engineered for very long fastening applications in harsh and corrosion‑prone environments, the M20‑2.50 × 140 mm hex cap screw is manufactured to DIN 933 specifications from A4 (316) stainless steel. The fully threaded shank allows maximum thread engagement through thick or multi‑layer assemblies, providing uniform clamping force and secure load transfer over extended lengths. A standard hex head supports 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 heavy industrial use. Commonly applied in heavy machinery, structural steel connections, equipment frames, and stainless steel fabrications where extended length, durability, and long service life are critical.
