Stainless steel quarter-turn fastener QCWEA series

springwith wedgethreaded

Product overview
Retractable ball-lock fasteners QCWEA provide positive locking for quick-change applications where frequent insertion and removal of a fixture is required. The retractable pin allows the fastener to clear the base when unlocked, enabling slide and door applications without interference. The fastener is used with matching ball-lock receptacles; rotating the knob a quarter turn expands the balls to lock the fixture and returning the knob to OFF retracts the balls to permit removal without tools.

Key features

• Retractable pin design for interference-free removal
• Quarter-turn operation: balls expand to lock, retract when turned OFF
• Sensor detection capable when paired with Position Sensor Receptacles (QCWE-M-S)
• Body: 303 stainless steel; Knob: 304 stainless steel; Wedge, balls and spring: stainless steel
• Designed for quick-change fixtures, slides and doors with frequent insertion/removal
