Gibraltar 57005XG Threaded Spring Plunger 1/4-20 Steel

Product Description

The GIBRALTAR 57005XG is a threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. It features a 1/4-20 thread size with a 1 inch thread length and a maximum plunger diameter of 0.118 inches. The plunger projects 3/16 inches and delivers 3 pounds of initial end force, increasing to 13 pounds of final end force under full compression. Both the body and nose are constructed from steel with a black finish. This part is sold individually and is commonly installed by machinists, maintenance technicians, and mechanical assemblers working with jigs, fixtures, and tooling components.

The 57005XG is suited for use in light industrial and precision mechanical applications where repeatable positioning or detent action is required. Typical install scenarios include machine tool fixtures, panel assemblies, and component alignment systems where a spring-loaded contact point is needed. The standard plunger length type and compact body length of 1 inch make it practical for tight-tolerance assemblies. No locking element is present, making removal and adjustment straightforward during setup or maintenance.

Key Features

• 1/4-20 thread size with 1 inch thread length for broad compatibility with standard tapped holes
• 3 pounds initial end force and 13 pounds final end force for controlled spring resistance
• 0.118 inch maximum plunger diameter with 3/16 inch projection
• Steel body and steel nose construction with black finish for durability and corrosion resistance in light-duty environments
• No locking element for tool-free adjustment and easy repositioning
• 5/64 inch hex drive for precise installation torque control

Compatibility

Designed as an OEM-style threaded spring plunger for use in any application requiring a 1/4-20 tapped hole and standard plunger geometry.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 1/4-20 hole using a 5/64 inch hex key. Ensure the mating assembly is depressurized or de-energized before installation in any active mechanical or pneumatic system. Do not overtighten, as excessive torque can damage the thread engagement or affect spring preload performance. Follow applicable machinery safety standards and lockout procedures when servicing assemblies containing spring plungers.
