Gibraltar 57082G Threaded Spring Plunger 5/8-11 Steel

Product Description

The GIBRALTAR 57082G is a threaded spring plunger designed for positioning, indexing, and locking applications in industrial and mechanical assemblies. It features a 5/8-11 thread size with a 1-1/2 inch thread length and a standard plunger projection of 5/16 inch. The steel body and steel nose deliver durability in demanding environments. With an initial end force of 10.5 pounds and a final end force of 25.5 pounds, this plunger provides consistent spring tension across its travel range. A built-in locking element holds the plunger position when required. Machinists, tool and die makers, and maintenance technicians install this type of component in fixtures, jigs, and mechanical stops.

The 57082G suits a wide range of industrial applications where repeatable positioning or detent action is needed. Common install scenarios include machine tool fixtures, assembly jigs, rotary indexing tables, and equipment panels requiring a positive lock. The black finish provides a measure of corrosion resistance for light-duty environmental exposure. The maximum plunger diameter is 0.31 inches, and the hex size for installation is 5/16 inch, allowing for straightforward installation with standard hand tools.

Key Features

• 5/8-11 thread size with 1-1/2 inch thread length for secure mounting in tapped holes
• Standard 5/16 inch plunger projection for consistent detent or indexing travel
• Steel body and steel nose construction for durability in industrial use
• Initial end force of 10.5 pounds and final end force of 25.5 pounds for reliable spring tension
• Integrated locking element to hold plunger in retracted or extended position
• Black finish for light corrosion resistance

Compatibility

Designed as a standard threaded spring plunger replacement or new installation component for industrial fixtures, jigs, and mechanical assemblies requiring a 5/8-11 threaded body with locking capability.

Installation Notes

Installation requires a properly tapped 5/8-11 threaded hole in the receiving body. Use the 5/16 inch hex drive to thread the plunger in by hand first, then torque to the assembly specification with an appropriate hex key. De-energize or lock out any powered equipment before servicing assemblies that contain spring plungers. Verify plunger projection and force requirements match the application before final installation.
