Precision Technology Supplies are one of the largest distributors of Stainless Steel Washers in Europe, both in Metric to DIN and ISO standards and American ANSI / ASME specifications. All are available to buy now online. Washers are usually flat and used essentially to distribute the load of a screw, bolt or nut and to prevent damage to the surface. Still the most popular, in Europe, are Metric Form A Flat Washers. The thinner Form B version are made to the old British Standard BS4320 but other Metric washers are now made to DIN and ISO standards. Penny washers (also known as Fender washers in the USA) with their large outer diameter are ideal to spread the load further for thin sheet metal or to make a connection where the hole has been enlarged through wear and tear. Shim washers are wafer thin flat washers used for precision spacing of parts in industries such as Aerospace, Defence, Electronics and Robotics. PTS has the largest Stainless Steel range on offer in Europe. We offer many different types of Spring Washers of which the most popular is a Spring Lock Washer to DIN 127B or ASME B18.2.1. These are circular rings split at a single point and bent into a helical shape. This maintains a spring force to create friction and resistance to rotation and are not generally used with a flat washer. Tooth Lock Washers, also known as a serrated washer or star washer, have serrations either internally or externally. These bite into the bearing surface and are especially effective on soft materials such as plastic or aluminium. We also have Europe's largest range of American SAE and 800 Series standard Washers which we have been supplying to both European distributors and OEM's worldwide since 1988.
