SS Button Head Cap Screw

SS Button Head Cap Screw is a low-profile socket cap screw manufactured from premium grade stainless steel (SS 304 / SS 316L), offering superior corrosion resistance for demanding environments. The smooth domed button head provides an attractive, flush finish on visible surfaces while the internal hex drive allows high torque application in confined spaces.

Conforming to ISO 7380 standards, these screws are ideal for marine fittings, food processing equipment, pharmaceutical machinery, outdoor structural assemblies, and any application where corrosion resistance and aesthetic appearance are both critical. Available in SS 304 for general corrosion resistance and SS 316L for marine and chemical environments.

Grade: ISO 7380 M3 – M24 SS304 / SS316L ISO 7380 Corrosion Resistant
