Steel cam lever QLCL

with tapped insertthreadedinternal thread

Product Overview
These cam lever fasteners provide quick tool-free fastening and unfastening. Compared to conventional cam handles, the QLCL series offers improved vibration resistance and a distinct tactile click at the clamping end. For stud-type variants the handle orientation can be set to any direction. Engage by threading like a conventional fastener; push the lever down for final tightening and pull the lever up to release clamping force and unthread.
