Celebrating 30 Years of Trading.
To mark 30 years of trading this month, we have reduced our carriage paid threshold to £30 nett.
Form A washers, also known as flat washers, and a standard sized washer most commonly used in metal-to-metal applications. Washers are used in conjunction with a threaded fastener i.e., a bolt and nut, to help prevent the screw from loosening and to distribute the load from the nut or bolt head more evenly and over a larger area. These washers are made to DIN 125A specifications.
