Kipp K0321.204 Threaded Ball Plunger M4 Steel

Product Description

The KIPP K0321.204 is a threaded ball plunger designed for indexing, positioning, and light detent applications in mechanical assemblies. The plunger features an M4 thread for installation into tapped holes and uses a spring-loaded steel ball to provide controlled resistance and tactile feedback. The steel ball measures 0.0984 inches (2.50 mm) in diameter with a maximum ball reach of 0.0315 inches (0.80 mm). Initial end force is 12 N and final end force is 22 N. The body length is 0.3543 inches (9.00 mm). A locking element is included to secure the plunger in position after installation. This component is installed by tooling specialists, machine builders, and maintenance technicians working with fixtures, jigs, and mechanical positioning systems.

The K0321.204 is suited for use in light-duty mechanical positioning assemblies where repeatable detent action is required. Typical applications include slide positioning, panel latching, and fixture registration in industrial and machine tool environments. The compact M4 threaded body allows installation in tight spaces where larger plungers are not practical. Both the body and ball are steel construction, making this plunger appropriate for environments requiring metal-to-metal contact surfaces.

Key Features

• M4 threaded body for direct installation into tapped holes
• Steel ball and steel body construction for durability in metal contact applications
• Spring-loaded ball with 12 N initial end force and 22 N final end force
• Maximum ball reach of 0.0315 inches (0.80 mm) for controlled engagement depth
• Integrated locking element to prevent loosening after installation
• Slotted installation type for easy tightening and adjustment with a flat-blade screwdriver

Compatibility

Designed as a standard M4 threaded ball plunger suitable for tapped M4 holes in mechanical assemblies, fixtures, jigs, and machine tool components requiring light detent or indexing action.

Installation Notes

Installation requires a tapped M4 hole in the mating component. Use a flat-blade screwdriver in the slotted drive to thread the plunger into place and engage the locking element to lock it at the desired depth. Ensure the mating surface or detent geometry is aligned with the ball centerline before final tightening. De-energize or lock out any associated machinery before servicing or replacing plungers in active assemblies.
