Vlier FRT625 Locking T Handle Plunger 5/8-11 Steel

Product Description

The VLIER FRT625 is a locking T-handle plunger designed for indexing, positioning, and locking applications in industrial machinery and assembly fixtures. Built from steel, this plunger features a 5/8-11 thread with a 1.7-inch thread length and a 2.5-inch body length. The plunger projects 0.625 inches and measures 0.375 inches in diameter, delivering an initial end force of 2.5 pounds and a final end force of 5 pounds. The T-handle design allows for tool-free operation and positive locking, making it a practical choice for frequent adjust-and-lock cycles in production or maintenance environments. Machinists, tooling technicians, and industrial maintenance professionals are the typical installers.

The FRT625 is suited for use in jigs, fixtures, machine guards, panels, and equipment enclosures where a hand-operated, spring-loaded plunger with a locking feature is required. The 5/8-11 thread size makes it compatible with standard threaded mounting holes in steel or aluminum assemblies. Its compact body length of 2.5 inches and 2.5-inch handle length allow installation in tight clearance envelopes without interference. This part is typically used in light to medium industrial settings where repeatable positioning under low force loads is needed.

Key Features

• Locking T-handle allows tool-free engagement and positive lock without additional hardware
• 5/8-11 thread with 1.7-inch thread length for secure mounting in standard tapped holes
• Steel body construction for durability in industrial environments
• 0.375-inch plunger diameter with 0.625-inch projection for reliable indexing depth
• 2.5-pound initial end force and 5-pound final end force for controlled spring resistance
• Compact 2.5-inch body length suits installations with limited clearance

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial jigs, fixtures, and equipment panels requiring a 5/8-11 threaded locking T-handle plunger.

Installation Notes

Installation is performed by tooling technicians or industrial maintenance personnel. Ensure the mating threaded hole is clean and free of debris before threading in the plunger body. Apply appropriate thread engagement depth based on the 1.7-inch thread length to avoid bottoming out. No special tools are required for hand installation, but a wrench may be used on the body if torque seating is needed per the application design.
