Kipp K0325.2A3 Threaded Ball Plunger 5/16-18 Steel

Product Description

The KIPP K0325.2A3 is a threaded ball plunger designed for positioning, indexing, and light detent applications in mechanical assemblies. The plunger features a 5/16-18 thread and a 5.00 mm (0.1969 inches) steel ball that extends up to 1.50 mm (0.0591 inches) beyond the body face at maximum reach. The steel body measures 0.7087 inches in length and incorporates a locking element to secure the plunger in place after installation. Initial end force is 47 N and final end force is 73 N, making it suitable for controlled-resistance positioning work. Installation is performed via hexagon socket drive.

This ball plunger is used in tooling fixtures, jigs, machine slides, and general industrial assemblies where repeatable part positioning or light detent action is required. The 5/16-18 thread size fits standard threaded bores in steel and aluminum workpieces. The locking element prevents the plunger from backing out under vibration or repeated cycling, which is critical in production environments and automated handling equipment.

Key Features

• 5/16-18 thread for installation into standard tapped bores
• Steel body and steel ball for durability in industrial environments
• Locking element prevents back-out under vibration or cycling loads
• 47 N initial end force and 73 N final end force for controlled detent resistance
• 0.0591 inch (1.50 mm) maximum ball reach for precise positioning geometry
• Hexagon socket installation for torque-controlled tightening with standard Allen keys

Compatibility

Designed as a standard replacement or direct-fit threaded ball plunger for 5/16-18 tapped bores in tooling fixtures, jigs, and mechanical assemblies requiring light detent or positioning function.

Installation Notes

Installation is performed using a hexagon socket (Allen key) sized to the drive recess in the plunger body. Ensure the mating threaded bore is clean and properly tapped to 5/16-18 specification before installation. Engage the locking element according to the assembly torque requirements for the application to prevent loosening during service. Relieve any spring preload and de-energize or lock out the host equipment before removing or replacing plungers in live assemblies.
