Manufactured for heavy‑duty metric fastening where corrosion resistance and extended grip length are critical, the M20‑2.50 × 85 mm hex cap screw is produced to DIN 933 specifications from A4 (316) stainless steel. The fully threaded shank provides full thread engagement through thick or multi‑layer assemblies, ensuring strong, uniform clamping force and reliable load distribution under high stress. A standard hex head allows secure installation and removal using common industrial tools. A4 (316) stainless steel offers excellent resistance to rust, moisture, salt exposure, and aggressive chemical environments, 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 durability, corrosion resistance, and long service life are essential.
