Say goodbye to annoying sticking, binding, or rubbing doors. Slide these shims behind your door’s hinge leaf to align it in the jamb, restoring smooth opening and closing. All are made of plastic to resist moisture and prevent rot. They have a universal hole pattern, so all you need to measure is your hinge height, and they can be cut with a knife for a perfect fit.

Stop socket head screws from wiggling loose on equipment with constant, vigorous vibration, such as engines, turbines, and generators. These washers have a small diameter to fit under screws with narrow heads. Similar to a spring, they flatten under pressure to add tension between mating surfaces. As long as the washers aren't deformed or otherwise damaged, you can reuse them indefinitely without losing locking strength. Also known as conical washers and Belleville washers.

Stack multiple washers in the same direction to double or triple how much weight they can bear. Stack washers in opposite directions for better deflection, which means they compress further and withstand more shock and movement without loosening.
