Flat washers are essential components placed beneath the head of a screw or bolt in an assembly, designed to evenly distribute the force over a broader area. These round, thin plates feature a center hole tailored to the specific size of the bolt or screw. Typically, flat washers are employed to spread the load of threaded bolts, screws, and nuts uniformly as the fastener is tightened, ensuring stability and durability in assemblies.
