M4 Penny Washers – Bright Zinc Plated (BZP) | Box of 100
These M4 penny washers are also known as repair washers or mudguard washers. They are manufactured from mild steel. In addition, each washer is finished with a bright zinc plated (BZP) coating for long-term corrosion resistance. Each washer has a 25mm outer diameter and a 4.5mm inner hole. As a result, they offer a large bearing surface that spreads the load of M4 bolts and screws. Therefore, they help prevent pull-through on thin, soft or damaged materials.
