Gibraltar SW10-8SL-PT-G Threaded Spring Plunger 1/2-13

Product Description

The GIBRALTAR SW10-8SL-PT-G is a stubby threaded spring plunger designed for positioning, indexing, and light-duty holding applications in mechanical assemblies. The plunger features a 1/2-13 thread size with a 0.75 inch thread length and a maximum plunger diameter of 0.248 inches. Projection measures 0.151 inches. The steel body and steel nose provide durable, consistent spring force across repeated cycles. A built-in locking element secures the plunger position within the threaded bore, preventing loosening from vibration. Initial end force is 1.75 pounds and final end force is 5.5 pounds. This part is installed by machinists, tool-and-die professionals, and mechanical assembly technicians.

The SW10-8SL-PT-G suits applications where a compact, stubby plunger profile is required in tight clearance conditions. The 0.75 inch body length keeps the overall installed footprint minimal, making it appropriate for jigs, fixtures, tooling plates, and machine components where space along the bolt axis is limited. The locking element makes this plunger well suited for environments with vibration or repeated cycling where a standard plunger might back out over time.

Key Features

• Stubby plunger body length of 0.75 inches for compact installation in space-constrained assemblies
• 1/2-13 thread size with 0.75 inch thread length for secure engagement in standard tapped holes
• Steel body and steel nose for wear resistance and long service life
• Built-in locking element prevents plunger from backing out under vibration
• Initial end force of 1.75 pounds and final end force of 5.5 pounds for controlled indexing resistance
• Maximum plunger diameter of 0.248 inches with 0.151 inch projection

Compatibility

Designed as a direct-install threaded spring plunger for any mechanical assembly or tooling application with a standard 1/2-13 tapped hole and sufficient clearance for a stubby-profile plunger body.

Installation Notes

Installation requires a properly tapped 1/2-13 through or blind hole in the mating component. Power down and de-energize any equipment before servicing assemblies containing spring plungers. Use appropriate hex or spanner tooling rated for the fastener size — do not overtighten, as this can distort the locking element or damage the plunger nose. Confirm plunger projection and spring force meet the application load requirements before finalizing installation.
