Gibraltar SSWPFN10-6B-G Press Fit Ball Plunger 0.375 in

Product Description

The GIBRALTAR SSWPFN10-6B-G is a press fit ball plunger designed for use in positioning, locating, and indexing applications across mechanical assemblies. The body is machined from stainless steel with a passivated finish, and the ball is nylon, measuring 0.312 inches in diameter. The plunger installs by pressing the flanged body into a drilled hole, eliminating the need for threading. Initial end force is 5 pounds and final end force is 14 pounds, making it suitable for light-duty detent and indexing work. Machinists, tool and die makers, and maintenance technicians are the typical installers.

This ball plunger fits applications where a threaded installation is not practical or desired. The flanged design seats against a mating surface to control insertion depth and resist axial pullout. Common use cases include machine tool fixtures, jigs, drawer slides, panel assemblies, and any mechanism requiring repeatable tactile positioning. The passivated stainless steel body offers corrosion resistance in light wash-down or humid environments. The nylon ball reduces marring on soft mating surfaces.

Key Features

• Press fit installation — no threading required, installs into a plain drilled hole
• Stainless steel body with passivated finish for corrosion resistance
• Nylon ball reduces surface marring on soft or coated mating parts
• Flange design controls insertion depth and resists pullout
• 5 pound initial force and 14 pound final force for light-duty detent applications
• Compact profile: 0.375 inches body diameter, 0.0786 inches body length

Compatibility

Designed as a press fit ball plunger for use in mechanical fixtures, jigs, machine tool assemblies, and similar indexing or positioning applications requiring a flanged, non-threaded body style.

Installation Notes

Installation requires pressing the plunger body into a correctly sized drilled hole using an arbor press or similar controlled-force tool — do not strike the ball or flange directly with a hammer. Verify hole diameter against the 0.375 inch body dimension to achieve proper press fit retention before pressing to full depth. The flange seats flush against the mating surface to set final depth automatically. No thread engagement or adhesive is required, but the hole bore finish and diameter tolerance are critical to retention force.
