Gibraltar 34261 Knob Handle Plunger 1/2-13 Non-locking

Product Description

The GIBRALTAR 34261 is a non-locking knob handle plunger with a threaded stud body, designed for indexing, positioning, and locating applications in industrial and mechanical assemblies. The plunger features a 1/2-13 thread size, a 0.875-inch thread length, and delivers an initial end force of 1.25 pounds ramping to a final end force of 5 pounds. The body measures 1.125 inches in length with a maximum plunger diameter of 0.31 inches and a plunger projection of 0.25 inches. Constructed from steel with a zinc-plated finish, the 34261 is installed by machinists, maintenance technicians, and industrial tradespeople wherever repeatable spring-loaded positioning is required.

The GIBRALTAR 34261 suits light-duty panel, fixture, and machine assembly work where a knobless threaded stud profile is needed. The stud thread size is 3/8-16, allowing direct installation into tapped bores. The 0.25-inch length under head or shoulder accommodates standard mounting configurations. Its compact body and defined spring force range make it appropriate for applications requiring controlled plunger engagement without a locking element override.

Compatibility

Designed as an OEM-style replacement or direct-install component for industrial fixtures, jigs, and mechanical assemblies requiring a 1/2-13 threaded non-locking spring plunger with a knobless stud body profile.

Installation Notes

Installation is performed by qualified maintenance technicians or machinists. De-energize and lock out any powered equipment before servicing assemblies containing this plunger. Thread the stud body into the appropriate 3/8-16 tapped bore using standard hand tools; do not overtighten, as this can restrict plunger travel. Verify plunger projection and spring force requirements match the application before final assembly.
