Gibraltar SWN10-5SL-G Threaded Spring Plunger 5/16-18

Product Description

The GIBRALTAR SWN10-5SL-G is a stubby-style threaded spring plunger designed to provide consistent, repeatable force for indexing, positioning, and light-duty detent applications. The steel body and steel nose deliver durability in industrial and mechanical assembly environments. The plunger features a 5/16-18 thread with a 0.562-inch thread length and a maximum plunger diameter of 0.135 inches, producing a 0.084-inch projection. Initial end force is 1.25 pounds and final end force is 4.00 pounds, making it suitable for low-force positioning tasks where a predictable spring rate matters. Installed by machinists, toolmakers, and mechanical assemblers, this part seats directly into a threaded bore with standard hand tools or a hex wrench.

The SWN10-5SL-G fits residential and commercial machine tool fixtures, jigs, and precision mechanical assemblies where a compact, threaded spring plunger is required. The stubby plunger length type is well suited for tight-clearance installations where a standard-length plunger body would not fit. No locking element is present, allowing the plunger to be threaded in and adjusted to the required engagement depth. Applications include panel assembly jigs, sliding door detents, and light indexing mechanisms across manufacturing and maintenance environments.

Key Features

• Stubby plunger length type for tight-clearance installations
• 5/16-18 thread size for compatibility with standard tapped bores
• 0.562-inch thread length provides secure engagement depth
• 1.25-pound initial end force and 4.00-pound final end force for predictable spring performance
• Steel body and steel nose for durability in industrial settings
• No locking element — allows field adjustment of engagement depth

Compatibility

Designed as an OEM-style replacement or direct-fit component for any threaded bore application requiring a 5/16-18 stubby spring plunger with a 0.562-inch thread length.

Installation Notes

Installation is performed by machinists or mechanical assemblers using standard hand tools or a hex wrench sized for the plunger body. Thread the plunger into a clean, pre-tapped 5/16-18 bore to the desired engagement depth. Do not overtighten, as excessive torque can damage the spring mechanism or distort the plunger body. Ensure the bore is free of debris before installation to maintain proper spring travel and seating.
