Stainless A2 and A4 fasteners, from stock.
A2 (AISI 304 type) covers most indoor and general-purpose applications; A4 (AISI 316 type) adds molybdenum for chloride and marine environments. Both are austenitic, non-magnetic and supplied to ISO 3506.
Our most-ordered range: stainless parts are the fastest-moving lines in our quotes, so DIN 912, DIN 934 / ISO 4032 and DIN 125-A are kept in stock from M1.6 to M36. For cleanrooms the same parts are available EPK-treated and vacuum-packed.
