M4 Allthread Rod, 316 Stainless Steel - ATRA4M4X1000

The Allthread Rod 316 Stainless Steel is available in 19 sizes (M4 to M48) and 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.

The A4 (316) grade is stainless steel with added molybdenum, which helps it hold up where salt, pool chemicals or washdown chemicals are present. It is the more corrosion-resistant of the two common stainless grades, at a higher cost than 304. Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.

The range runs to 19 variants, covering sizes M4 to M48.

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

Key specifications

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. Where chlorides are not a concern, the A2 (304) version costs less: Allthread Rod 304 Stainless Steel.
