Penny Washers A2 Stainless Steel - Large Flat Mudguard Repair Fender Washers DIN 9021

Achieve a stronger, more secure fastening while protecting your surfaces with our premium A2 Stainless Steel DIN 9021 Penny Washers.

Whether you're a professional tradesperson, an automotive enthusiast, or a dedicated DIYer, these large-diameter flat washers are an essential component for any project. Their significantly increased outer diameter distributes the load from screws and bolts over a wider area, preventing damage and ensuring a long-lasting, reliable connection.

• MAXIMUM LOAD DISTRIBUTION: The extra-wide surface area (Form G) is specifically designed to prevent fastener heads from pulling through or damaging soft materials. Perfect for use on wood, plastic, rubber, sheet metal, and composites.

• THE ULTIMATE REPAIR WASHER: Ideal for maintenance and repair work. The large diameter effectively covers oversized, worn, or corroded holes, providing a secure new bearing surface and saving you from costly replacements.

• VERSATILE APPLICATIONS: A must-have for a huge range of jobs. Commonly used as mudguard/fender washers in the automotive industry, as well as for construction, decking, furniture assembly, plumbing, and general repairs.

• PRECISION ENGINEERED: Manufactured to the strict dimensional specifications of DIN 9021, guaranteeing consistent size, quality, and performance for every washer.
