Vlier SSSD62 Threaded Spring Plunger 5/8-11 Stainless Steel

Product Description

The VLIER SSSD62 is a threaded spring plunger designed for use in precision indexing, positioning, and locking applications across industrial and mechanical assemblies. It features a 5/8-11 thread with a 1-1/2 inch thread length and a standard-length stainless steel body. The plunger nose is Delrin, providing a durable, low-friction contact point. Initial end force is 10.5 pounds and final end force is 25.5 pounds, making this unit suitable for applications requiring consistent, repeatable spring-loaded positioning force. The plunger diameter ranges from 0.308 to 0.310 inches with a 5/16 inch projection. Machinists, toolmakers, and mechanical assembly technicians are the primary installers of this component.

The SSSD62 is used in jigs, fixtures, machine tool components, and industrial equipment where a spring-loaded plunger is needed to locate, detent, or retain a moving part. The stainless steel body makes it appropriate for environments with moisture exposure or where corrosion resistance is required. Its standard plunger length suits most general-purpose threaded plunger bore configurations. No locking element is included, which allows free rotation during installation and adjustment.

Key Features

• 5/8-11 thread size with 1-1/2 inch thread and body length for deep engagement
• Stainless steel body for corrosion resistance in wet or industrial environments
• Delrin nose material provides low-friction, wear-resistant plunger contact
• 10.5 pound initial end force and 25.5 pound final end force for consistent detent action
• Plunger diameter of 0.308 to 0.310 inches with 5/16 inch projection
• No locking element allows straightforward installation and repositioning

Compatibility

Designed as an OEM-style or replacement threaded spring plunger for standard 5/8-11 threaded bores in industrial jigs, fixtures, and mechanical assemblies.

Installation Notes

Installation is performed by machinists or mechanical assembly technicians using standard hand tools. Thread the plunger into a pre-tapped 5/8-11 bore to the desired depth before securing in position. Do not overtighten, as this can compress the internal spring beyond its rated travel and reduce service life. Verify bore thread condition before installation to ensure full thread engagement.
