Stainless Steel Fasteners
Stainless Steel Fasteners Supplier in India
A2 and A4 stainless steel fasteners in the -50 and -70 property classes, M6 to M64 metric and 1/4" to 2-1/2" imperial, passivated to ASTM A380.
Product Range
Stainless steel fasteners are specified wherever corrosion resistance matters more than raw strength — marine hardware, chemical-processing plant, food and pharma equipment, coastal structures, and any humid or washdown environment where mild or high-tensile steel would rust. Kesharia stocks SS hex bolts in A2 (SS 304) and A4 (SS 316 molybdenum-alloyed) grades, in both A2-50/A4-50 and the higher-strength A2-70/A4-70 property classes, across the full M6 to M64 metric range and 1/4" to 2-1/2" imperial range. Metric sizes are supplied to DIN 931, DIN 933, DIN 601, DIN 558, DIN 960, DIN 961, DIN 7990, ISO 4014, ISO 4015, ISO 4016 and ISO 4017; imperial sizes to ASME B18.2.1 and AS 1390. All bolts are passivated per ASTM A380 to reinforce the native chromium-oxide layer. Custom lengths and non-standard threads are manufactured to drawing.
