Product Details

Stainless Steel 316L Hex Bolts, Nuts & Washers 1. Product Description (Pointwise) SS 316L is a low-carbon austenitic stainless steel alloyed with molybdenum, offering excellent corrosion resistance, especially against chlorides. Low carbon ("L") content minimizes the risk of intergranular corrosion after welding or heat exposure. SS 316L hex bolts, nuts, and washers are suitable for marine, chemical, and coastal environments where long service life is critical. Supplied in metric and inch sizes, with full-thread or half-thread options as per standards or drawings. 2.
