Vlier SSSD50 Threaded Spring Plunger 8-32 Stainless Steel

Product Description

The VLIER SSSD50 is a threaded spring plunger designed for precision positioning, indexing, and light-duty locking applications in mechanical assemblies. The body is machined from stainless steel with a Delrin nose, giving it corrosion resistance alongside a non-marring contact point. It carries an initial end force of 2.7 pounds and a final end force of 7.3 pounds, making it suited for applications that require consistent, repeatable spring tension. The 8-32 thread allows installation into standard tapped holes. Machinists, toolmakers, and mechanical assemblers are the primary installers of this hardware.

This plunger fits into tapped 8-32 holes in fixtures, jigs, machine frames, and enclosures where a spring-loaded detent or positioning point is needed. The stainless steel body handles environments with exposure to moisture, coolants, or mild chemicals. Standard projection is 3/32 inches, and thread length is 5/8 inches. It is sold individually and used in both light industrial and precision instrument assembly contexts where controlled engagement force and corrosion resistance are priorities.

Key Features

• Stainless steel body for corrosion resistance in wet or chemical-exposed environments
• Delrin nose provides non-marring, low-friction contact with mating surfaces
• Initial end force of 2.7 pounds and final end force of 7.3 pounds for controlled detent engagement
• Standard 8-32 thread for direct installation into common tapped holes
• 3/32 inch plunger projection suitable for light indexing and positioning duties
• No locking element - allows easy torque-in installation without staking or adhesive

Compatibility

Designed as a standard-thread spring plunger for use in any mechanical assembly or fixture that accepts an 8-32 tapped hole and requires a spring-loaded detent point with stainless steel construction.

Installation Notes

Installation requires a properly tapped 8-32 hole in the receiving component. Use an appropriate hex key or slotted driver per the drive style of the plunger body, and avoid over-torquing, which can damage the thread or compress the spring beyond its design range. Ensure the mating surface and hole are clean and free of debris before threading in. No special codes govern installation, but standard mechanical assembly practices for threaded hardware apply.
