Gibraltar 34244SS Locking Plunger 1/4-20 Threaded Stud

Product Description

The GIBRALTAR 34244SS is a locking knob-style plunger with a knobless threaded stud configuration, designed for indexing, positioning, and workholding applications in industrial and mechanical assemblies. The plunger operates on a 1/4-20 thread with a 0.5-inch thread length and delivers an initial end force of 0.50 pounds rising to a final end force of 1.50 pounds. The maximum plunger diameter measures 0.1440 inches with a diameter tolerance of plus 0.0010 inches. A built-in locking element holds the plunger in the retracted position, preventing unintended extension during setup or transport. Machinists, millwrights, and mechanical assembly technicians are the typical installers of this component.

The 34244SS fits applications where a low-profile, knobless interface is required and the plunger must be actuated or locked via the threaded stud rather than a traditional knob. Common use cases include fixture plates, jigs, machine guarding panels, and equipment enclosures where space constraints or tooling clearance make a protruding knob impractical. The stud thread size of 10-32 allows direct installation into pre-tapped holes or with a mating nut. This plunger is suited for light-duty clamping and detent positioning in both OEM machinery builds and field maintenance applications.

Key Features

• Locking element holds plunger retracted to prevent unintended extension
• Knobless threaded stud design for low-profile, space-constrained installations
• 1/4-20 external thread with 0.5-inch thread length for secure mounting
• Initial end force of 0.50 pounds and final end force of 1.50 pounds for light-duty detent applications
• 10-32 stud thread size allows installation into standard pre-tapped holes or with a mating nut
• Plunger projection of 0.1250 inches and overall plunger length of 1.0620 inches

Compatibility

Designed as an OEM-style replacement or new-install component for light-duty indexing and positioning assemblies requiring a 1/4-20 locking plunger with a knobless threaded stud interface.

Installation Notes

Installation is typically performed by machinists or mechanical assembly technicians using standard hand tools. Ensure the mating tapped hole or nut matches the 1/4-20 thread specification before installation. Disengage any loaded mechanisms and relieve spring force before removing or replacing the plunger assembly. Do not exceed the rated end force range, as overloading the locking element may cause premature wear or failure of the detent mechanism.
