A head washer is a precision-dimensioned flat washer used at fastener locations where load distribution and correct clamping force are critical to a secure assembly. By spreading the load of a bolt or nut across a defined contact area, this washer helps maintain consistent clamping pressure and protects the mating surface from damage or deformation. When a washer of the wrong size or thickness is used, fastener torque cannot be properly achieved, which can lead to loosening, leaks, or structural failure at that joint over time.
