Gibraltar SWN10-6S-PT-G Threaded Spring Plunger 3/8-16

Product Description

The GIBRALTAR SWN10-6S-PT-G is a stubby threaded spring plunger designed for precise positioning, indexing, and light-duty locking applications in mechanical assemblies. The plunger features a steel body with a nylon nose, a 3/8-16 thread size, and a thread length of 0.625 inches. It delivers an initial end force of 4.5 pounds and a final end force of 18.5 pounds, making it suitable for repeatable detent and hold functions. A built-in locking element secures the plunger in the threaded bore once installed, preventing back-out under vibration or repeated cycling. Machinists, tool and die technicians, and mechanical assemblers commonly install this type of component.

This spring plunger is used in fixtures, jigs, tooling plates, and machine components where a compact stubby-length plunger is required. The 0.625-inch body length suits installations with limited depth clearance. The nylon nose protects mating surfaces from marring, making it appropriate for assemblies where contact surfaces must remain undamaged. It is suited for both light industrial and precision mechanical applications where controlled detent force and positive retention are required.

Key Features

• Stubby plunger length type at 0.625 inches for shallow-bore installations
• Steel body construction for durability and thread integrity
• Nylon nose material protects mating surfaces from damage
• Locking element prevents back-out under vibration
• 4.5 pound initial end force and 18.5 pound final end force for controlled detent action
• Standard 3/8-16 thread for broad compatibility with threaded bore applications

Compatibility

Designed as an OEM-style replacement or direct-fit component for threaded spring plunger applications using a 3/8-16 thread size and stubby body length in mechanical fixtures, jigs, and tooling assemblies.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 3/8-16 bore using the appropriate hex key or spanner tool per the manufacturer's drive configuration. Ensure the bore depth and thread engagement length match the 0.625-inch thread length before installation. The locking element should be tightened to the specified seating torque recommended by the fixture designer or OEM documentation. Do not overtighten, as this may damage the locking element or distort the plunger body.
