Gibraltar MSW10-5BLCZ-PTG Threaded Ball Plunger M8x1.25

Product Description

The GIBRALTAR MSW10-5BLCZ-PTG is a threaded ball plunger designed for indexing, positioning, and light detent applications in mechanical assemblies. It features an M8x1.25 thread, a steel body, and a steel ball measuring 0.196 inches in diameter. The locking element secures the plunger at a set position within the threaded bore, preventing back-out under vibration or repeated cycling. Initial end force is 1.12 pounds and final end force is 2.25 pounds, giving the installer a defined resistance range for the application. Maximum ball reach is 0.059 inches. At 0.05 pounds, it is a lightweight hardware component suited to precision assemblies.

This ball plunger is used in manufacturing fixtures, tooling jigs, machine tool components, and industrial equipment where repeatable positioning or light-load detent action is required. The M8x1.25 thread is a standard metric coarse thread, making this plunger compatible with a wide range of threaded housings in both OEM production and MRO maintenance environments. The purple color code aids in visual identification during assembly and kitting operations.

Key Features

• M8x1.25 metric coarse thread for broad housing compatibility
• Steel body and steel ball for durability in industrial environments
• Locking element prevents back-out under vibration
• Defined force range: 1.12 pounds initial to 2.25 pounds final end force
• Maximum ball reach of 0.059 inches for controlled detent travel
• Purple color code for easy visual identification during assembly

Compatibility

Designed as a standard metric threaded ball plunger for use in any threaded bore with an M8x1.25 internal thread in mechanical fixtures, tooling, and industrial equipment assemblies.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped M8x1.25 bore using an appropriate wrench or hex key on the body flats. Ensure the mating bore is clean and free of debris before installation. The locking element should be engaged to the specified torque range recommended by the assembly drawing or equipment manufacturer. Do not exceed the maximum ball reach specification, as overextension may damage the detent mechanism.
