internal threadadjustablewith external thread

Description
These cam action lever fasteners provide rapid, tool-free fastening and unfastening in confined spaces. The compact design and stud-type handle—adjustable to any direction—allow reliable clamping where access is limited. Thread like a conventional fastener; perform final tightening by pushing the cam lever down. Pull the lever up to release clamping force and unthread the fastener as needed. Handles and studs are 300 series stainless steel; washers are 304 stainless steel.

Operation

• Thread engagement to position the fastener
• Push lever down for final clamping (cam action)
• Pull lever up to release clamping force and unthread
