These cam action lever fasteners allow for quick fastening and unfastening without the use of tools. Actuating the handle causes the elastomer spring to expand against the surrounding surface. The expansion of the spring can be adjusted using the nut, ensuring consistent clamping forces each time the cam lever is used. To unfasten, the handle is pulled up to contract the spring. These cam levers are ideal for quick change operations where plates or covers are secured. The handle is made from fiberglass reinforced black plastic. The hinge pin is made from stainless steel with a natural finish. The stud and washer are made from steel with a blue chromate finish. The spring is made from a PUR elastomer.
