Vision Alloys are the leading manufacturer of high integrity special fasteners (e.g. bolts, set screws, stud-bolts, nuts and washers), meeting clients’ exacting demands for critical applications in hostile environments. Whether for offshore (buoyancy and petrochemical), seawater, pump, valve or nuclear, the demands for an exceptional service and supply is never ending. We believe manufacturing bolting in exotic materials is an art form and it is something we have perfected at Vision Alloys.

Our 304 Stainless Steel Fasteners product range includes 304 Stainless Steel Bolts, Hexagon head bolt, Hexagon head screw, Round head square neck bolt, Hexagon socket head cap screw in full thread and half thread, Hexagon wood screw, Hexagon socket button head screw, Hexagon socket button flange screw, Hexagon socket counter sunk head cap screw in full thread and half thread, square nuts, square weld nuts, hexagon weld nuts, thick nyloc nuts, hexagon flange nuts, threaded rods, dowel screws,Plain / Flat Washer, Spring Washers, Countersunk Washer,Tooth Lock Washer and many more. We provide products as per DIN, ANSI, JIS standards.

Stainless steel of grade 304 contains nickel of 8% and chromium of 18% and is the most commonly used grade for the production of fasteners. It possesses an excellent combination of strength, corrosion resistance and fabricability. Fasteners of this grade are being extensively used today in almost every industry.
