Value Collection 530-4238 5C Square Steel Collet 19/32 in

Product Description

The VALUE COLLECTION 530-4238 is a 5C square steel collet designed for precision workholding on lathes and other spindle-driven machine tools equipped with 5C collet systems. It accepts 19/32-inch square stock and holds a true indicator reading (TIR) of 0.0005 inches, making it suitable for applications where concentricity and repeatability matter. The internal thread measures 1.041 inches at 24 threads per inch, and the external thread measures 1.242 inches at 20 threads per inch. Constructed from steel throughout, this collet is sized for shops and machine operators running square bar stock or square-profile workpieces through a standard 5C spindle nose.

This collet fits standard 5C collet chucks and collet closers used in production turning, screw machine work, and secondary operations on square stock. It is commonly used in job shops and manufacturing environments where 5C tooling is the shop standard. The 19/32-inch square capacity suits bar stock or part blanks with a square cross-section at that size. Machinists and toolroom technicians are the primary users.

Key Features

• 19/32-inch square collet capacity for square bar stock and workpieces

• Steel construction for durability in production environments
• 5C collet form factor — widely supported across lathe and collet chuck platforms

Compatibility

Designed as an OEM-style replacement or direct-fit collet for machine tools equipped with a standard 5C collet spindle nose and compatible collet closer or chuck.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel familiar with 5C collet systems. Power down and lock out the machine spindle before inserting or removing any collet. Inspect the collet bore and spindle nose for chips or debris before seating the collet, as contamination directly affects TIR and part accuracy. Do not exceed the rated collet capacity, as overloading a collet can damage both the collet and the spindle nose.
