A rack bolt screw is a combination-type fastener with machine thread on one side and wood/concrete fixing thread or plug arrangement on the other, designed to anchor sanitary fixtures securely.​
It is usually supplied as a complete set including 2 bolts, plastic wall plugs (fisher), nuts, washers, and decorative caps for neat installation.​

Basic construction and material

Most rack bolts are made from mild steel or stainless steel, often with zinc, nickel, or chromate plating for corrosion resistance in wet bathroom environments.​
Common grades include SS202 and SS304 in stainless steel, and they may be polished or galvanized depending on quality and application.​

Typical sizes and set contents

For sanitary fittings, popular diameters are around M10–M12 with lengths in the 100–165 mm range, supplied as pairs.​
A standard wash basin or EWC rack bolt set generally includes 2 full-threaded bolts, 2 nylon or plastic wall plugs, 2–4 washers, and 2 metal or plastic end caps.​

Main applications

Rack bolt screws are used for mounting wall-hung wash basins, floor or wall-mounted closets, geysers, and other heavy sanitary accessories to masonry or concrete.​
They provide strong load-bearing capacity (often up to several hundred kg per set) and help keep fixtures rigid, level, and safe during long-term use.​
