introduction to products：

White Zinc Plated Wedge Anchors are heavy-duty fasteners designed for securing objects to concrete, masonry, or stone. They consist of a threaded rod with a cone-shaped wedge at one end and a nut and washer at the other. Made from carbon steel (grades 4.8–8.8 for general use), the white zinc plating provides reliable corrosion resistance, making them suitable for indoor, dry, or moderately damp environments like warehouses, retail spaces, or commercial buildings.

When installed, the wedge expands against the base material as the nut is tightened, creating a secure, permanent hold. Available in sizes from M6 to M24, they’re widely used to mount electrical panels, HVAC units, shelving systems, and safety barriers to concrete floors or walls, ensuring stable fastening in structural applications.

Instructions for Use：

First, drill a hole in the base material (concrete/masonry) using a carbide-tipped drill bit, with a diameter matching the anchor size (e.g., M10 anchor needs a 10mm hole). Clean the hole to remove dust and debris. Insert the wedge anchor into the hole, ensuring the washer and nut are loosely attached to the threaded end. Use a wrench to tighten the nut—this pulls the cone wedge up, expanding the anchor against the hole walls until secure. Do not over-tighten, as this may damage the anchor or base material.
