M8 x 40 mm Hex Nut Sleeve Anchor, 316 Stainless Steel - SANA4M8X40

The Hex Nut Sleeve Anchor, 316 Stainless Steel is available in 11 sizes (M6.5 to M12) and is a sleeve anchor with a hex nut and flange that expands in drilled masonry or concrete as the nut is tightened.

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. Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.

This listing has 11 variants covering sizes M6.5 to M12 and lengths 35 mm to 100 mm. Variants are supplied in packs of 25 to 100, depending on size.

Austenitic stainless steel is generally non-magnetic, although cold-worked parts can show weak magnetism. Use stainless washers and nuts with stainless fasteners, so the whole joint is made of the same material.
