Stainless Steel Bolt and Nut Selection Checklist
Select stainless steel bolts and nuts by the specified material grade, standard and actual operating environment. SS 304 and SS 316 are common corrosion-resistant options, but suitability depends on chlorides, cleaning chemicals, temperature and exposure; neither is universally corrosion-proof. SS 202 should not be substituted for SS 304 or SS 316 without engineering approval. When a drawing specifies ISO or DIN dimensions, also confirm the required mechanical property class where applicable.
Dimensions, Thread Pitch and Matching Sets
For hex bolts, provide the nominal diameter, under-head length, metric coarse or fine pitch and whether full-thread or partial-thread construction is required. The existing DIN 933 / ISO 4017 listing relates to fully threaded hex bolts; other head styles and standards require explicit specification. For matching nuts, give the approved nut standard, thread and quantity per bolt. State any required washers, surface finish, passivation, coating or galling-control provisions rather than assuming that every bolt-and-nut set includes them.
What to Include in an SS Bolt and Nut RFQ
- SS grade (for example SS 304 or SS 316), applicable standard and any required property class
- Bolt head style, diameter, length, thread pitch and threading extent
- Matching nut specification and the number of nuts and washers per assembly
- Finish, process environment, quantity, delivery destination and drawing if non-standard
- Material-test or inspection documents where the purchase specification requires them
For long threaded components, see SS Studs and Threaded Rods; for other grades, browse the Industrial Fasteners range. Request an SS bolt and nut supplier quotation in Chennai against your project specification.
