1/2" BSW Allthread Rod, 316 Stainless Steel - ATRA412BSWX3
Available
The Allthread Rod BSW 316 Stainless Steel is a straight rod threaded along its full length. It is cut to length and used with nuts and washers to hang, tie, clamp or span between two fixing points.
This listing is a single size: 1/2".
Supplied in 316 (A4) stainless steel. The molybdenum in A4 gives better resistance to chlorides than A2 (304), so it is the usual choice near the coast, around pools and in marine and food-processing environments. BSW (British Standard Whitworth) is an older inch-based thread found on older machinery and imported equipment. It is not interchangeable with UNC or metric threads.
Austenitic stainless steel is generally non-magnetic, although cold-worked parts can show weak magnetism. Stainless threads can gall (seize) when tightened under load or at speed. A smear of anti-seize on the thread and a steady tightening speed reduce the risk.

Selecting the right option
Match the thread system to the nuts and fittings you already have: metric coarse, metric fine, UNC and BSW rods are not interchangeable. Cut rods can leave a burr, so run a nut over the cut end before use. For indoor and general outdoor use where chlorides are not a concern, the A2 (304) version is the lower-cost option: Allthread Rod BSW 304 Stainless Steel.
