M12 x 13.40mm - Penny Washers - A2 Stainless Steel | Vital Parts - WPE-M12-30-A2

Our M12 Stainless Steel Penny Washers, also known as Repair Washers or Mudguard Washers, are designed for use in applications requiring a wider surface area to distribute load. Commonly paired with bolts, machine screws and nuts, these washers are essential for reducing stress on softer materials and preventing pull-through, especially on wood, plastic, or thin sheet metal.

This product has a large outer diameter relative to its internal hole, offering enhanced load distribution and surface protection. Manufactured from high-grade stainless steel to BS 4320 standards, our washers are available in A2 (304) and A4 (316 marine grade) stainless steel in metric sizes from M4 x 12 to M12 x 50.

What are M12 Stainless Steel Penny Washers?

M12 Stainless Steel Penny Washers are flat washers with a significantly larger external diameter than standard washers. Their main function is to spread the clamping force of a fastener over a wider area, helping to prevent damage to the material and creating a more secure, longer-lasting joint. Especially useful in repair jobs or when working with softer materials, they are a staple in both DIY and professional construction projects.
