Gibraltar 10021 Threaded Ball Plunger 5/8-11 Steel

Product Description

The GIBRALTAR 10021 is a threaded ball plunger designed for positioning, indexing, and light-duty detent applications in mechanical assemblies. The plunger features a 5/8-11 thread, a 0.375-inch steel ball, and a steel body finished in black. It delivers 9 pounds of initial end force and 18 pounds of final end force, making it suitable for controlled resistance applications. A built-in locking element secures the plunger at the set depth once installed. Machinists, maintenance technicians, and mechanical assemblers install this type of component in fixtures, jigs, and machine housings where repeatable positioning is required.

The GIBRALTAR 10021 is used in industrial and light manufacturing settings where a spring-loaded ball detent is needed to hold or index moving parts. Its 5/8-11 thread allows installation into standard tapped holes in steel, aluminum, or cast housings. The black finish provides basic corrosion resistance for indoor use. The locking element prevents the plunger from backing out under vibration or repeated cycling, which is a common requirement in fixture and tooling work.

Key Features

• 5/8-11 threaded body for installation in standard tapped holes
• 0.375-inch diameter steel ball for consistent detent contact
• 9-pound initial end force and 18-pound final end force for controlled indexing resistance
• Locking element prevents back-out under vibration or cycling
• Black finish on steel body for indoor industrial use
• Body length of 63/64 inch (0.9844 inches) with 0.096-inch maximum ball reach

Compatibility

Designed as a standard threaded ball plunger for use in any application requiring a 5/8-11 tapped hole detent or positioning element in steel, aluminum, or cast housings.

Installation Notes

Install into a properly tapped 5/8-11 hole using an appropriate wrench or driver on the hex body. Ensure the mating hole is clean and free of chips before threading in. The locking element should be engaged to the specified torque range per the installer's fixture design requirements. No special tools beyond standard hand tools are typically required for installation.
