These Lipped Square Plate Washers are designed specifically for use in strut channel systems, providing enhanced load distribution and a secure, anti-rotation fit. Available in M6, M8, M10, and M12 sizes with a Bright Zinc Plated (BZP) finish, they offer a clean appearance and moderate corrosion resistance, making them ideal for indoor and light industrial environments.
The lipped design allows the washer to sit securely within the channel profile, preventing movement or spinning during installation. Combined with the strength and surface coverage of a square plate washer, they deliver a reliable solution for fastening channel nuts, threaded rods, brackets, and other components within Unistrut-type framing systems.
