The page lists the product as an "M5 Repair Washer 20mm x 1.5mm BZP." While specific uses are not detailed on this product page, repair washers are generally used to provide a larger bearing surface under a fastener, distributing the load over a wider area and preventing pull-through or damage to softer materials. The "M5" indicates it is designed for M5 bolts.
BZP stands for Bright Zinc Plated. This coating provides a level of corrosion resistance, making the washer more durable and suitable for various applications, including those in outdoor or agricultural environments where it might be exposed to moisture.
