Value Collection 530-4334 5C Hex Steel Collet 17/32 in

Product Description

The VALUE COLLECTION 530-4334 is a 5C hex collet machined from steel, designed to grip hex stock at a nominal 17/32 inch across-flats size. It delivers a total indicator reading (TIR) of 0.0005 inches, providing consistent, repeatable workpiece concentricity in production turning and machining operations. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, conforming to standard 5C collet interface dimensions. This collet is installed by machinists and toolroom technicians in lathes, collet closers, and indexing fixtures that accept the 5C collet system.

This collet is suited for holding hex bar stock and hex-profile workpieces during turning, threading, and secondary machining operations. It fits into standard 5C-compatible spindles found on engine lathes, turret lathes, and manual or CNC collet closers used in production and job-shop environments. The hex geometry prevents workpiece rotation during machining without requiring additional fixturing, making it practical for high-volume runs on hex-profile parts.

Key Features

• Hex collet profile grips hex stock without rotation, eliminating secondary clamping
• 0.0005 inch TIR for consistent concentricity across production runs
• 1.041 inch-24 internal thread conforms to standard 5C interface
• 1.242 inch-20 external thread for standard 5C collet closer compatibility
• Steel construction for durability under repeated clamping cycles

Compatibility

Designed as a standard 5C-pattern replacement collet compatible with lathes, collet closers, and indexing fixtures that accept the 5C collet system and a 17/32 inch hex workpiece size.

Installation Notes

Installation is performed by machinists using standard 5C collet closers or draw-tube spindle assemblies. Always disengage the spindle and confirm the machine is fully powered down before inserting or removing a collet. Inspect the collet bore and spindle taper for chips or burrs before seating the collet, as contamination directly affects TIR. Do not exceed the collet nominal grip range, as over-clamping a collet on undersized stock will accelerate bore wear.
