Home / Washers / Recess Washers / Cup Washers Product Description No.12 / M6 Cup Washers - A2 Stainless SteelCup Washers, similarly to Countersunk Washers, allow for a Countersunk Screw to sit flush inside them and therefore can be used on a flat surface that might not otherwise accommodate them. Due to their high sides, Cup Washers offer a level of tampering protection to the screw whilst also providing a smooth and decorative finish to the fastening. Cup Washers, un-like the solid Countersunk Washer, are hollow on the inside meaning they are lightweight and mainly used for an aesthetic finish. These Cup Washers are to fit both a No.12 Countersunk Screw & an M6 Countersunk Bolt..These Cup Washers are made from A2 Stainless Steel which provides corrosion and oxidation resistance.For larger quantities or items not listed, please email sales@gwr-fasteners.co.uk and one of our team will provide you with a quotation.
