M4 x 10mm O/D Countersunk Washers - 6082 Aluminium Anodised Black

Countersunk Washers, similarly to Cup Washers, offer a smooth decorative finish to a fastening, whilst also allowing Countersunk Screws to be used on flat surfaces that may not accommodate them.

Due to their high sides, Countersunk Washers also offer a level of tampering protection to the screw. Countersunk Washers, however, are a solid and more heavy-duty washer in comparison and therefore offer a better distribution of force across the bearing surface.

These Countersunk Washers have been precision manufactured in house from high quality 6082 Aluminium Bar using state of the art CNC machines. Due to this, unless the item is deemed faulty, this item is non-returnable and non-refundable.
