Gibraltar 34032 Locking Plunger 1/4-20 1/2 Inch Thread

Product Description

The GIBRALTAR 34032 is a locking knob handle plunger with a threaded stud body and no external knob. It is designed for positioning, indexing, and clamping applications in industrial fixtures, jigs, and machine assemblies. The body threads at 1/4-20 with a 0.5-inch thread length and a 5/8-inch length under the head. The steel plunger locks in place via an internal locking element, resisting unintended retraction under load. Initial end force is 0.5 pounds and final end force is 2.5 pounds. A zinc-plated finish provides basic corrosion resistance. Machinists, toolmakers, and maintenance technicians install this type of component in light-duty fixturing and positioning systems.

The 34032 is suited for use in manually adjusted fixtures, dies, and jigs where a compact, threadable plunger stop is needed. The knobless threaded stud design allows the unit to be installed flush or recessed into a tapped bore without a protruding knob interfering with workpiece clearance. The 1/8-inch plunger projection and 0.124-inch maximum plunger diameter make it appropriate for fine-pitch indexing applications where a small-diameter ball or pin engagement point is required.

Key Features

• Locking plunger type holds position and resists retraction without external force
• Knobless threaded stud body installs flush into tapped bores for low-profile clearance
• 1/4-20 external thread with 0.5-inch thread length for secure mounting engagement
• Stud thread size of 10-32 for locking element integration
• End force range of 0.5 to 2.5 pounds suits light-duty indexing and positioning
• Steel construction with zinc-plated finish for durability and basic corrosion resistance

Compatibility

Designed as a standard locking plunger replacement or new installation component for industrial fixtures, jigs, and positioning assemblies requiring a 1/4-20 threaded mount with a knobless stud body.

Installation Notes

Installation requires a tapped 1/4-20 through or blind hole in the fixture body. De-energize or lock out any associated machinery before installing or servicing plunger components in production fixtures. Use appropriate thread engagement depth to avoid bottoming the stud before the head seats. Verify plunger projection and locking force are adequate for the intended indexing application before placing the fixture into service.
