The 100‑piece M10 grey expansion wall plug set is designed for reliable, heavy‑duty anchoring across a variety of substrates including concrete, solid brick and aerated blocks. Each plug expands securely when the screw is driven in, ensuring a snug fit that resists rotation and pull‑out under load—key for mounting shelves, brackets or mechanical fixtures. Finished in neutral grey, these plugs blend with most surfaces and offer a professional look while delivering excellent performance. The bulk 100‑piece pack makes it ideal for contractors, installers or large‑scale jobs where consistency and value matter. Simple to use: just drill to the correct diameter, insert the plug flush with the surface, and drive in your screw for a strong, long‑lasting fix.
