M20‑2.50 × 130 mm Hex Cap Screw – Stainless Steel A4 (316), DIN 933

Built for very long, high‑load metric fastening in corrosive and industrial environments, the M20‑2.50 × 130 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 reliable clamping force and stable load distribution across extended fastening spans. A standard hex head allows secure tightening and removal using conventional industrial hand or power tools. Thanks to its A4 (316) stainless steel construction, this fastener offers exceptional resistance to rust, moisture, salt exposure, and chemical attack. Commonly used in heavy machinery, structural steel assemblies, offshore and marine equipment, and stainless steel fabrications where extended length, corrosion resistance, and long service life are essential.
