Washers Information

We understand that your success depends on a responsive and reliable parts supplier. This inventory includes all of the standard variations in flat, spring and toothed washers in both metric and imperial sizes.

In addition we can supply many of the application specific washers such as;

Belleville Washers: A conical shaped spring disc. Used to maintain load or tension in bolted assemblies.
Beveled Washers: A flat washer which can be square or circular with one bearing surface having an oblique angle. Commonly used when fastening bolts through the flanges of "I" beams.
Countersunk Finishing Washers: A formed circular washer designed for use with flat or oval head screws. Designed for accommodating the heads of countersunk screws. It provides additional bearing area on the material being fastened and can be used to give a neat, finished appearance.
F436 Hardened Washers: A hardened steel washer manufactured in accordance with ASTM Standard F436. Designed for general-purpose mechanical and structural use with bolts, nuts, studs, and other internally and externally threaded fasteners.
Fender Washers: A flat washer with significantly more surface area than a USS or SAE washer, but made from thinner gauge steel than most flat washers. Used where an extra wide bearing surface is required. Originally designed for auto body work, they are also used in sheet metal, plumbing, and electrical work.
Machine Screw Washers: The smallest type of flat washer with an outside diameter equal to slightly twice the size of the inside diameter. Designed for use with machine screws in general industrial applications.
Metric Fender Washers (DIN 9021): A thin, flat, circular washer with a centrally located hole which is approximately 6% wider than the hole of a like-sized metric flat washer. Generally manufactured in accordance with DIN Standard 9021
Metric Flat Washers, Extra Thick (DIN 7349): A thin, flat, circular washer with a centrally located hole. Generally manufactured in accordance with DIN Standard 7349.
Metric Flat Washers, Hardened Thrust (DIN 6340): A thin, flat, circular washer with a centrally located hole. Generally manufactured in accordance with DIN Standard 6340.
Metric Flat Washers, Shaft (DIN 1440): A thin, flat, circular washer with a centrally located hole. Generally manufactured in accordance with DIN Standard 1440.
Metric Flat Washers, Small O.D. (DIN 433): A thin, flat, circular washer with a centrally located hole. Generally manufactured in accordance with DIN Standard 433.
Metric Flat Washers, Standard (DIN 125): A thin, flat, circular washer with a centrally located hole. Generally manufactured in accordance with DIN Standard 125.
Metric Split Lock Washers (DIN 127): A coiled, hardened, split circular washer with a slightly trapezoidal wire section, for use with metric screws. Generally manufactured in accordance with DIN Standard 127.
SAE Flat Washers: Similar to a USS washer, but with slightly smaller inside and outside diameters and made from thinner materials than USS washers. Designed to meet the requirements in the field of automotive engineering.
Split Lock Washers: A coiled, hardened, split circular washer with a slightly trapezoidal wire section. Preferred lock washer for use with hardened bearing surfaces. Applies greater bolt tension per unit of torque. Provides a hardened bearing surface, creating more uniform torque control. Provides more uniform load distribution. Resists loosening cause d by vibration and corrosion.
Tooth Lock Washers: A hardened circular washer with twisted prongs or teeth protruding from the inside and/or the outer edges of the washer. Preferred lock washer for use with hardened bearing surfaces. Applies greater bolt tension per unit of torque. Provides a hardened bearing surface, creating more uniform torque control. Provides more uniform load distribution. Resists loosening cause d by vibration and corrosion. Internal tooth are preferred when a finished appearance is crucial since the teeth are hidden under the head of the screw. External tooth offer greater locking efficiency since the teeth are on the largest radius and provide greater tensional resistance.
USS Flat Washers: A thin, flat, circular washer with a centrally located hole. Designed to meet the majority of industrial applications in manufacturing, maintenance, and repair.
