Gibraltar 67003G Threaded Spring Plunger M6x1 Steel Body

Product Description

The GIBRALTAR 67003G is a threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. It features an M6x1 thread with a 25 mm thread length and a 3.02 mm maximum plunger diameter. The plunger delivers 2.98 pounds of initial end force and 12.90 pounds of final end force, making it suitable for consistent, repeatable detent positioning. Both the body and nose are constructed from steel for durability in industrial and machine-tool environments. Machinists, tool-and-die technicians, and mechanical assemblers typically install this component during fixture or jig assembly.

The GIBRALTAR 67003G is used in machine frames, fixtures, jigs, and tooling plates where a spring-loaded plunger is needed to hold a position or index a moving component. With a 5 mm plunger projection and a compact 25 mm body length, it fits standard tapped M6x1 bores found in a wide range of light and medium industrial equipment. It is well suited for repetitive manual positioning tasks on assembly lines and machining centers.

Key Features

• M6x1 thread size with 25 mm thread length for standard metric tapped holes
• 3.02 mm maximum plunger diameter with 5 mm projection
• 2.98 lb initial end force and 12.90 lb final end force for reliable detent engagement
• Steel body and steel nose construction for wear resistance
• 3 mm hex size for installation and removal with a hex key
• No locking element — free-spinning installation for straightforward fitment

Compatibility

Designed as a direct-fit replacement or new-installation threaded spring plunger for any application with a standard M6x1 tapped bore requiring a steel-body plunger with a 25 mm thread length.

Installation Notes

Install using a 3 mm hex key into a clean, properly tapped M6x1 through-hole or blind bore. De-energize or lock out any moving assembly before installing or removing the plunger to prevent uncontrolled movement. Do not overtighten — apply only enough torque to seat the body flush or to the desired depth, as excessive force can damage the thread or affect plunger travel. Confirm plunger projection is unobstructed after installation before returning the assembly to service.
