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

Product Description

The GIBRALTAR MSW10-5BLCZ-G is a threaded ball plunger with an M8 x 1.25 thread size, designed for use in indexing, positioning, and light-duty detent applications in mechanical assemblies. The steel body and steel ball provide durability in demanding industrial and shop environments. With a ball diameter of 0.196 inches, a body length of 0.63 inches, and a maximum ball reach of 0.059 inches, this plunger fits into compact assemblies where space is limited. Initial end force is 1.12 pounds and final end force is 2.25 pounds, making it suitable for light spring-loaded positioning tasks. Machinists, toolmakers, and maintenance technicians are the typical installers.

This ball plunger is used in jigs, fixtures, machine slides, and tooling plates where a spring-loaded ball is needed to hold a component in a detent position. The M8 x 1.25 thread allows installation into standard metric-threaded holes. The purple color code identifies this specific force and size variant within the product family, aiding in quick identification when multiple plunger specifications are in use at the same location.

Key Features

Compatibility

Designed as a standard metric threaded ball plunger suitable for jigs, fixtures, tooling plates, and mechanical assemblies requiring an M8 x 1.25 threaded detent or positioning element.

Installation Notes

Ball plungers are typically installed by machinists or maintenance technicians using a hex key or spanner wrench on the plunger body. Ensure the receiving bore is clean and threaded to M8 x 1.25 specification before installation. Do not overtighten, as excessive torque can damage the spring mechanism or thread. Verify ball reach and spring force are appropriate for the detent load before finalizing the assembly.
