Install with a hex key for more torque than slotted long-nose spring plungers.

Slotted on both ends for installation with a screwdriver.

Install these spring plungers with a screwdriver—they're slotted on one or both ends.

Retract the nose by pulling the knob.

Quickly align, join, or hold machine components in place in food, pharmaceutical, and other sanitary environments. Pulling the plunger knob and twisting it 90° will lock the nose into its retracted position.

Lock the nose into the retracted position by pulling the ring and rotating it 90°.

Thread onto machinery or attach a knob or handle to the threaded spindle.

Install by hand or with a hex key in low-clearance applications.

Use an arbor press or similar pressure tool to install these spring plungers into a panel.

The base flares out during installation, creating a backside flange in hard materials and near edges in panels up to 0.312" thick. Install with a flare-in installation tool and an arbor press.

Install in soft material such as aluminum and low-carbon steel at least 0.036" thick with an arbor press or similar pressure tool.

A spring-loaded toggle holds against the back of the material.

A shallow head makes these bolts good for low-clearance applications.
