Retractable, Quarter-Turn Knob Locking Pins
Featuring a retractable shank for slide or door applications and ball-lock clamping
Fixtureworks (Frasier, MI), a leading supplier of workholding and fixturing technologies now offers Retractable Knob-locking Pins that lock and unlock with a quarter turn of the knob. The retractable shaft on these fasteners allows them to safely slide off from a base without interference, making them ideal for slide and door applications. This new QCWEA series fastener will not release until the knob is turned to the "OFF" position, allowing the balls to retract into the shank and allowing the shank to be raised out of the way of the base plate for no interference all without the use of tools. There is also a sensor detector that confirms if it's locked. These pins feature ball-lock system for firm clamping force up to 11 lb. (50N). QCWEA retractable, quarter-turn pins are made from stainless steel.
