Vlier SSMD62N Threaded Spring Plunger 5/8-11 Stainless

Product Description

The VLIER SSMD62N is a stubby-style threaded spring plunger designed for positioning, indexing, and light-duty locking applications in precision assemblies. The body is machined from stainless steel, and the nose is made from Delrin, providing corrosion resistance and low-friction contact in a compact form factor. Thread size is 5/8-11 with a thread length of 1.062 inches. The plunger delivers 7 pounds of initial end force and 50 pounds of final end force, making it suitable for applications that require firm, repeatable detent engagement. A locking element is included to secure the plunger in position after adjustment. This part is typically installed by machinists, toolmakers, or maintenance technicians.

The SSMD62N is used in jigs, fixtures, tooling plates, machine tool components, and industrial equipment where controlled spring-loaded positioning or detent action is required. The stubby plunger profile suits confined spaces where a standard-length plunger body will not fit. The Delrin nose minimizes surface marring on mating workpieces. This plunger is sold individually and installs directly into a tapped 5/8-11 threaded hole.

Key Features

• Stainless steel body for corrosion resistance in demanding environments
• Delrin nose material reduces surface damage to mating components
• Stubby plunger length suits tight or recessed installation spaces
• Locking element secures plunger setting after adjustment
• 7-pound initial end force and 50-pound final end force for firm detent engagement
• 5/8-11 thread installs directly into standard tapped holes

Compatibility

Designed as a direct-install spring plunger for any application with a tapped 5/8-11 through-hole or blind hole of sufficient depth to accept the 1.062-inch thread length.

Installation Notes

Installation is performed by threading the plunger body into a pre-tapped 5/8-11 hole using a hex key or spanner wrench on the body flats. Torque the body to seat the locking element before final adjustment of plunger projection. Ensure the mating hole is clean and free of chips or debris before installation. No special codes govern spring plunger installation, but follow the equipment manufacturer's assembly procedures for torque and alignment requirements.
