Gibraltar 34164 Knob Handle Plunger 1/4-20 Stainless

Product Description

The GIBRALTAR 34164 is a non-locking knob handle plunger with a knobless threaded stud design, built from stainless steel with a zinc finish. It features a 1/4-20 thread size with a 0.5-inch thread length and a maximum plunger diameter of 0.124 inches. The plunger delivers an initial end force of 1 pound and a final end force of 5 pounds, making it suitable for light-duty indexing and positioning applications in machinery, fixtures, and assemblies. A locking element is incorporated into the design. This part is installed by machinists, maintenance technicians, and mechanical assemblers in industrial and manufacturing environments.

The GIBRALTAR 34164 is used in machine tool setups, jigs, fixtures, and mechanical assemblies where controlled spring-loaded plunger action is required. The threaded stud mount allows direct installation into tapped holes without the need for a separate knob, keeping the profile low. The 1/8-inch plunger projection and 1.062-inch plunger length suit compact fitment scenarios where space is limited. Typical applications include panel positioning, drawer stops, and index pin assemblies in light industrial equipment.

Key Features

• Non-locking plunger type for smooth, repeatable engagement and release
• Knobless threaded stud design (10-32 stud thread) for low-profile direct mounting
• Stainless steel construction with zinc finish for corrosion resistance in industrial environments
• 1 pound initial end force to 5 pounds final end force for controlled spring resistance
• Plunger diameter tolerance of plus 0.001 inches for precise fit in indexed assemblies
• Locking element included to secure the plunger position as required

Compatibility

Designed for installation into tapped 1/4-20 threaded holes in machine fixtures, jigs, and mechanical assemblies requiring a non-locking spring plunger with a knobless stud mount.

Installation Notes

Installation is performed by machinists or mechanical assemblers using a standard wrench or driver sized for the 10-32 stud thread. Ensure the receiving tapped hole is clean and properly sized to the 1/4-20 specification before threading in the plunger. De-energize or lock out any associated equipment before servicing or replacing spring plungers in active machinery. Do not exceed the rated final end force to avoid damage to the plunger or the mating detent.
