These cam action lever fasteners allow for quick fastening and unfastening without the use of tools. Their compact design provides easy clamping in unclamping in tighter spaces. The handle position of the stud-type handle can be set to any desired direction. Tighten by threading like a traditional fastener however, for final tightening the cam lever is pushed downward. To unfasten, the cam lever is pulled up releasing clamping force and allowing the fastener to be unthreaded. They are ideal for quick change operations where parts only have to be loosened and not completely unassembled. Handle and studs are made from 300 series stainless steel. The washers are made from 304 stainless steel.
