Washers
Subcategories
-
Fender Washers
Fender Washers have a smaller inner diameter than Flat Washers to provide a greater bearing surface under the fastener. This helps prevent a nut, bolt or screw from pulling through the material. They also usually have a thinner guage.
-
Flat Washers
Flat Washers are circular cuts of steel with a hole cut out of the center in order to provide a larger bearing surface for scres and bolts.
-
Lock Washers, External Tooth
External Tooth Lockwashers have teeth around the outside of the washer to provide greater tortion resistance.
-
Lock Washers, Internal Tooth
Internal Tooth Lockwashers have teeth on the inside of the washer and are generally used with smaller fasterners to provide more grip by biting into the fastener and the work surface area.
-
Lock Washers, Split
Split Lockwashers are made from a metal coil that provides tention on the bolt even if it is slightly loose. When tightened completely, the washer is flat.
-
Square Nuts
Square nuts have been replaced by hex nuts for the most part, but they are still available for general purpose applications.
