Gibraltar 10009P-G Threaded Ball Plunger 1/4-20 Steel

Product Description

The GIBRALTAR 10009P-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. The plunger features a 1/4-20 thread for straightforward installation into a tapped hole, a steel body with a black finish, and a steel ball measuring 0.125 inches in diameter. Initial end force is 3 pounds, rising to a final end force of 7 pounds at full compression. Maximum ball reach is 0.035 inches. This type of component is installed by machinists, maintenance technicians, and mechanical assemblers in fixtures, jigs, slides, and similar hardware.

Threaded ball plungers like the 10009P-G are used across a wide range of industrial and mechanical applications where a spring-loaded detent is needed to hold a position, provide tactile feedback, or resist incidental movement. Common install scenarios include machine tool fixtures, drawer slides, panel assemblies, and positioning jigs. The black finish and steel construction suit general shop and light industrial environments. The 0.5313-inch body length accommodates typical thread engagement depths found in standard fixture plates and machined blocks.

Key Features

• 1/4-20 thread for direct installation into standard tapped holes
• Steel body with black finish for durability in shop environments
• Steel ball, 0.125 inches in diameter, with 0.035 inches maximum reach
• 3-pound initial end force and 7-pound final end force for light-duty detent applications
• No locking element — torque to hand-tight or with a hex key depending on body style
• Compact 0.5313-inch body length suits thin fixture plates and shallow bores

Compatibility

Designed as a standard-thread ball plunger for use in any application requiring a 1/4-20 threaded detent component in a steel body configuration.

Installation Notes

Installation requires a properly tapped 1/4-20 hole in the receiving material. Thread the plunger in by hand first to verify alignment, then tighten with the appropriate tool to avoid cross-threading or over-torquing the steel body. Ensure the ball side faces the detent surface before final seating. No special certifications or code requirements typically govern this hardware component, but follow any applicable equipment manufacturer guidelines for fixture assembly.
