M8 x 50 mm Stud Anchor, 316 Stainless Steel - STAA4M8X50

Made in 316 (A4) stainless steel, the Stud Anchor is a through-bolt style expansion anchor with a threaded stud, a nut and washer, and an expansion clip. It is set in drilled concrete by tightening the nut.

Made from 316 (A4) stainless steel, the grade normally specified for chloride-exposed work such as coastal installations, swimming pools, marine fittings and food-processing plant. Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.

This listing has 18 variants covering sizes M8 to M20 and lengths 50 mm to 180 mm. Pack quantities depend on size: packs of 10 to 50.

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.
