Gibraltar 67004G Threaded Spring Plunger M8 X 1.25

Product Description

The GIBRALTAR 67004G is a threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. The plunger features an M8 x 1.25 thread with a 25 mm thread length and a 3.43 mm maximum plunger diameter with a 5 mm projection. The steel body and steel nose deliver consistent spring force, rated at 2.98 pounds initial end force and 14.88 pounds final end force. This part is installed by machinists, tool-and-die technicians, and maintenance mechanics in fixtures, jigs, and production equipment where repeatable detent or stop positions are required.

The 67004G is suited for use in machine fixtures, workholding devices, tooling plates, and similar assemblies that require controlled spring-loaded plunger action. The M8 x 1.25 thread size is a common metric standard, making this plunger compatible with a wide range of metric-threaded housings in both light manufacturing and industrial maintenance applications. No locking element is included, so the plunger threads directly into a prepared M8 x 1.25 tapped hole without the need for additional retention hardware.

Key Features

• M8 x 1.25 thread with 25 mm thread length for secure installation in metric-tapped bores
• 5 mm plunger projection provides positive detent engagement in indexing applications
• 2.98 pounds initial end force and 14.88 pounds final end force for controlled spring resistance
• Steel body and steel nose construction for durability in production and fixture environments
• No locking element design allows straightforward installation and removal with a 4 mm hex key

Compatibility

Designed for installation in any M8 x 1.25 metric-tapped housing where a spring plunger with a 5 mm projection and steel construction is required. Verify thread depth and housing material before installation.

Installation Notes

Installation is performed by threading the plunger into a prepared M8 x 1.25 tapped hole using a 4 mm hex key. Ensure the receiving bore is clean and free of chips or debris before threading in the plunger. De-energize or lock out any machine before servicing fixturing components. Do not overtighten, as excessive torque can damage the thread or compress the internal spring mechanism.
