Value Collection 530-4350 5C Hex Steel Collet 25/32 in

Product Description

The VALUE COLLECTION 530-4350 is a 5C hex collet machined from steel, designed for workholding applications on lathes and other spindle-driven machine tools equipped with a 5C collet system. The collet accepts hex stock at 25/32 inch across flats and holds a total indicator runout (TIR) of 0.0005 inch, delivering the concentricity required for precision turning, milling, and secondary operations on hex-profile workpieces. The internal thread measures 1.041 inch-24 and the external thread measures 1.242 inch-20, matching standard 5C spindle nose specifications. Machinists and tool-room technicians install this collet where accurate hex stock gripping is needed without special fixturing.

This 5C hex collet is suited for production and job-shop environments running bar stock, fastener blanks, or any hex-profile part that requires repeatable positioning. It is compatible with any machine fitted with a standard 5C spindle, including engine lathes, turret lathes, and collet-close fixtures. The hex profile prevents rotation of the workpiece during operations such as cross-drilling, milling flats, or turning concentric diameters on hex stock. One collet is supplied per package.

Key Features

• 25/32 inch hex capacity for gripping hex-profile bar stock and workpieces
• 0.0005 inch TIR for precise concentricity and repeatable positioning
• Steel construction for durability under production workholding loads
• 1.041 inch-24 internal thread and 1.242 inch-20 external thread match standard 5C spindle specifications
• Standard 5C collet form fits a wide range of lathes and collet-close fixtures

Compatibility

Designed as an OEM-style replacement or supplementary collet for machine tool spindles using the standard 5C collet system.

Installation Notes

Installation is performed by qualified machinists or tool-room technicians. Power down and lock out the machine spindle before inserting or removing any collet. Inspect the collet bore, taper, and threads for chips or burrs before seating, and clean the spindle nose thoroughly to ensure full seating and accurate TIR. Do not exceed the rated stock capacity, as overloading a collet can damage both the collet and the spindle nose.
