Value Collection 530-4332 5C Hex Steel Collet 1/2 Inch

Product Description

The VALUE COLLECTION 530-4332 is a 5C hex collet machined from steel for use in 5C-compatible spindles and collet chucks found on lathes, indexers, and rotary fixtures. It holds hex stock at 1/2 inch across-flats and runs with a total indicator reading (TIR) of 0.0005 inches, supporting accurate, repeatable workholding on hex-profile parts. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, conforming to standard 5C collet thread geometry. Machinists and tool-room technicians install this collet when turning or milling operations require secure grip on hex bar stock or hex-profile workpieces.

This collet is suited for production and job-shop environments running 5C spindle equipment. Typical applications include secondary operations on hex fastener blanks, hex shaft turning, and fixturing hex stock on manual or CNC lathes equipped with 5C closers. The hex form prevents workpiece rotation under cutting loads, making it a reliable choice when round collets are not appropriate for the stock geometry.

Key Features

• Hex collet profile holds 1/2 inch hex stock securely without workpiece rotation
• Low TIR of 0.0005 inches supports accurate, repeatable part positioning
• Standard 5C thread geometry: 1.041 inches-24 internal, 1.242 inches-20 external
• Steel construction for durability in production machining environments
• Compatible with standard 5C spindles, chucks, and indexing fixtures

Compatibility

Designed as a standard 5C-pattern hex collet for use in any machine spindle, collet chuck, or indexing head that accepts 5C collets with 1.041 inches-24 internal and 1.242 inches-20 external thread specifications.

Installation Notes

Installation is performed by qualified machinists familiar with 5C collet equipment. Before inserting or removing the collet, ensure the spindle draw bar or collet closer is fully released and the machine is powered down and locked out per facility lockout/tagout procedures. Inspect the collet bore and spindle taper for chips or burrs before seating the collet, as debris will affect runout. Do not overtighten the draw bar beyond the equipment manufacturer's recommended feel, as this can distort the collet bore.
