M5 Hex Weld Nut, 316 Stainless Steel - XWNA4M5

The Hex Weld Nut A4 (316) is available in 5 sizes (M5 to M12) and is a hex nut with projections on one face that are resistance welded to sheet or plate. It leaves a fixed internal thread for a bolt or screw.

The range runs to 5 variants, covering sizes M5 to M12. Variants are supplied in packs of 50 to 100, depending on size.

A4 (316) stainless steel contains molybdenum (about 2 to 3 per cent), which improves its resistance to chlorides. It is the grade normally chosen for coastal, pool, marine and food-processing settings, and it costs more than A2 (304). Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.

Use stainless washers and nuts with stainless fasteners, so the whole joint is made of the same material.

Key specifications

Selecting the right option

Weld nuts are intended for welding in place, so welding procedure, filler and weld process should suit stainless steel. Check the weld projection arrangement against your process.
