Manufactured from A4 stainless steel (316), the M30‑3.50 x 140 mm DIN 933 hex cap screw is engineered for very long‑length, high‑load metric fastening where exceptional corrosion resistance and structural durability are required. The full‑thread (FT) design provides uninterrupted thread engagement along the entire shank, promoting uniform clamping force and dependable joint integrity in thick structural members and heavy industrial assemblies. A standard hex head supports precise torque application with metric tooling, enabling controlled and repeatable installation. Commonly specified for marine infrastructure, chemical processing equipment, outdoor structural connections, and heavy machinery, this fastener delivers extended service life and reliable performance in environments exposed to moisture, chemicals, and aggressive corrosive elements.
