Honesty Steel & Alloys Ltd. is a trusted manufacturer, exporter and supplier of Stainless Steel 310/310S Fasteners, offering high-quality industrial fastening solutions for demanding applications involving elevated temperatures, oxidation and corrosion.

Our SS 310/310S Fasteners are manufactured according to applicable ASTM, ASME, DIN, ISO, BS and other international requirements, subject to customer specifications. We supply fasteners in different sizes, threads, finishes, head configurations and material conditions for industrial, engineering, fabrication and high-temperature applications.

At Honesty Steel & Alloys Ltd., we supply Stainless Steel 310/310S Fasteners in standard and customized sizes. Our range includes hex bolts, heavy hex bolts, hex nuts, heavy hex nuts, machine screws, socket head cap screws, stud bolts, threaded rods, flat washers, spring washers, U bolts, anchor bolts and customized fasteners.

SS 310/310S Hex Bolts feature six-sided heads and are designed for installation with standard spanners or wrenches. They are available in different diameters, lengths and thread configurations.

SS 310 Fasteners are manufactured from Grade 310 stainless steel and are particularly suited for high-temperature environments. They can be supplied as bolts, nuts, screws, washers, stud bolts and threaded rods in different dimensions and thread configurations. SS 310S Fasteners use the low-carbon version of Grade 310. The reduced carbon content makes 310S preferable for many fabricated and welded applications where minimizing carbide precipitation is important. SS 310S nuts, bolts and other fasteners provide excellent resistance to oxidation and good performance in elevated-temperature service.
