Vlier SSM60N Threaded Spring Plunger 1/2-13 Stainless Steel

Product Description

The VLIER SSM60N is a stubby threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. Featuring a 1/2-13 thread with a 0.75-inch thread length, the plunger delivers an initial end force of 5 pounds and a final end force of 28 pounds. The body and nose are both constructed from stainless steel, providing corrosion resistance in demanding environments. The unit includes a locking element that secures the plunger in the threaded bore after installation. Maximum plunger diameter is 0.248 inches with a projection of 0.151 inches. This part is installed by mechanical assemblers, maintenance technicians, and tooling specialists across industrial and manufacturing settings.

The SSM60N is suited for use in fixtures, jigs, tooling plates, and precision mechanical assemblies where repeatable positioning or detent action is required. Its stubby body length of 0.75 inches makes it appropriate for installations with limited axial depth. The stainless steel construction supports use in wash-down, light chemical, or high-humidity environments where carbon steel components would be at risk of corrosion.

Key Features

• 1/2-13 thread size with 0.75-inch thread length for standard threaded bore installation
• Stubby plunger profile at 0.75-inch body length for space-constrained applications
• 5-pound initial end force and 28-pound final end force for reliable detent and positioning
• Stainless steel body and nose for corrosion resistance in demanding environments
• Locking element secures the plunger in the bore without adhesive or secondary fasteners
• 0.248-inch maximum plunger diameter with 0.151-inch projection

Compatibility

Designed as an OEM-style threaded spring plunger for installation in any 1/2-13 threaded bore requiring stubby-length detent or positioning action.

Installation Notes

Installation is performed using a standard hex wrench or spanner tool appropriate for the plunger body. Power down or de-energize any associated machinery before installing or removing spring plungers in active assemblies. The locking element engages the bore threads to resist back-out - do not apply thread-locking compounds unless specifically required by the assembly specification. Verify bore thread condition and cleanliness before installation to ensure proper seating and force values.
