Value Collection 530-4310 5C Hex Steel Collet 5/32 in

Product Description

The VALUE COLLECTION 530-4310 is a 5C hex collet machined from steel for use in 5C-compatible spindles and collet chucks. It accepts hex stock measuring 5/32 inch across flats and holds that stock with a total indicator runout (TIR) of 0.0005 inch, delivering the concentricity that precision turning, milling, and secondary operations demand. The internal thread measures 1.041 inch-24 and the external thread measures 1.242 inch-20, matching standard 5C closer and drawbar configurations. Machinists and toolroom technicians reach for this collet when gripping small hex bar stock for screw machine work, lathe operations, or fixture holding.

This collet is suited for light industrial and precision machining environments where hex-profile workholding is required. It is a common choice on turret lathes, screw machines, and manual or CNC lathes equipped with 5C spindle noses. Applications include secondary operations on hex fastener blanks, small-part turning, and production runs calling for repeatable hex stock registration. The 5/32-inch hex capacity makes it appropriate for small-diameter work common in instrument machining, medical component work, and precision hardware production.

Key Features

• Hex collet profile accepts 5/32-inch hex stock across flats
• 0.0005-inch TIR for consistent concentricity in precision applications
• Steel construction for durability under repeated clamping cycles
• 1.041 inch-24 internal thread matches standard 5C closer nuts
• 1.242 inch-20 external thread compatible with standard 5C drawbar setups
• Single-piece package quantity suitable for individual toolroom or production use

Compatibility

Designed as an OEM-style replacement or direct-fit collet for machine spindles and fixtures built to the standard 5C collet interface specification.

Installation Notes

Installation is performed by a machinist or toolroom technician familiar with 5C workholding systems. Power down and de-energize the machine spindle before seating or removing the collet. Thread engagement should be smooth and free of cross-threading; inspect threads on both the collet and the closer for wear or damage before installation. Do not force the collet into the spindle nose, as this can damage the seating taper and degrade runout performance.
