Gibraltar 67012G Threaded Spring Plunger M8 X 1.25

Product Description

The GIBRALTAR 67012G is a threaded spring plunger designed for indexing, positioning, and locating applications in mechanical assemblies. The plunger features an M8 x 1.25 thread with a 25 mm thread length, a 3.43 mm maximum plunger diameter, and a 5 mm projection. The steel body and steel nose provide durability in demanding environments. With an initial end force of 1.5 pounds and a final end force of 4.48 pounds, this plunger delivers reliable spring-loaded retention force. The black finish adds a basic level of surface protection. Machinists, toolmakers, and mechanical assembly technicians are the primary installers of this component.

The 67012G is suited for use in machine tool fixtures, jigs, workholding devices, and general mechanical assemblies requiring repeatable part positioning. The M8 x 1.25 thread allows installation into standard metric-tapped holes. It is applicable in both light industrial and precision manufacturing settings where controlled spring force and consistent plunger projection are required. No locking element is included, making this a standard free-spinning threaded plunger suitable for applications where post-installation adjustment may be needed.

Compatibility

Designed as an OEM-style replacement or new-installation threaded spring plunger for metric M8 x 1.25 tapped holes in mechanical fixtures, jigs, and positioning assemblies.

Installation Notes

Installation is typically performed by machinists or mechanical assembly technicians using a hex key in the 4 mm hex socket. Thread the plunger into a clean, properly tapped M8 x 1.25 hole and tighten to the desired position. Ensure the mating bore is free of debris before installation to prevent damage to the plunger nose. De-energize or lock out any machinery before servicing fixtures or assemblies containing this component.
