Quarter-Turn Locking Pull Pins are also known as spring plungers, hand retractable spring plungers, or locking Quick-Release pins.
The Quick-Release Pull Pin body is threaded into the application, with ring on outside surface. Pull the ring to retract spring-loaded tip, and turn 90° to lock the pin into the retracted position to allow adjustments. Twist the ring 90° back into place to allow the nose to spring forward and lock Pull Pin tip into desired hole location. Chamfered tip allows for easy alignment. Spring Plungers are ideal for adjustable tubing, tooling, latches, fixtures, gates, and much more. Steel Lanyards or Nylon Lanyards may be added to the Spring Plunger ring as a low cost “pull actuator”.
A high-quality imported pin provides dependable functionality at a competitive price.
Quick-Release Pull Pins are stocked in low carbon steel, zinc plated. Special sizes and materials, or domestic versions, can be made in-house.
Ask about our NEW Auto-Lock Safety Pull Pin! The new Pull Pin features a retractable tip that locks into an extended (forward) position automatically. Conventional spring-loaded Pull Pins and hand retractable spring plungers do not lock forward, allowing unintended retraction and disengagement due to vibration, movement and irregular mating holes. Our new forward-locked design means that the tip remains in an extended, locked position until manually disengaged by pulling the ring.
