Sachiya Steel International is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 304 Nuts And Bolts, which is an austenitic chromium nickel stainless steel. Stainless Steel 304 Hex Head Bolts is non – magnetic in the annealed condition but it becomes magnetic when cold worked. Stainless Steel 304 Hex Head Nuts is used for aircraft structural parts, architectural & automotive trim, automobile wheel covers, conveyor belts & appliances. The sizes and thickness of Stainless Steel 304 Square Bolts usually furnished to excellent specification, inclusive, in minimum wall thickness or, if specified in the order, average wall thickness.
The combination between ductility & toughness of Stainless Steel 304 Square Nuts is excellent even at low temperature, where its weldability is also good. Stainless Steel 304 U-Bolts having other diameters may be furnished, provided such fasteners comply with all other requirements of this specification. Stainless Steel 304 Lock Nuts has slightly higher carbon version than SS 314, which is further widely used in the stamping, spinning & wire forming industry.
Stainless Steel 304 Eye Bolts is used to form washer & springs, which is mainly used in parts requiring cold forming after machining. Stainless Steel 304 Eye Nuts provides excellent toughness and is frequently used for aircraft fittings, electrical switchgear components etc. Stainless Steel 304 T-Bolts offers excellent machinability, good strength & corrosion resistance.
