Value Collection 530-4236 5C Square Steel Collet 9/16 in

Product Description

The VALUE COLLECTION 530-4236 is a 5C square steel collet designed for use in 5C-compatible collet chucks and fixtures on manual and CNC lathes, indexers, and rotary tables. This collet holds square workpieces with a 9/16 inch jaw opening and delivers a total indicated runout (TIR) of 0.0005 inches, providing the concentricity required for close-tolerance turning and secondary operations. The internal thread is 1.041 inches-24 and the external thread is 1.242 inches-20, both standard dimensions for 5C tooling systems. Machined from steel for durability under repeated clamping cycles, this collet is installed by machinists and toolroom technicians working on production or job-shop equipment.

This collet is suited for holding square bar stock or square-profiled workpieces in 5C-style spindles during turning, milling, grinding, or inspection operations. It is a practical choice for shops running 5C collet closers on engine lathes or 5C indexing fixtures where accurate, repeatable workholding on square stock is required. The 9/16 inch capacity accommodates common square bar sizes within that dimension.

Key Features

• 9/16 inch square jaw opening for holding square-profiled workpieces
• 0.0005 inch TIR for precise, repeatable concentricity
• 1.041 inches-24 internal thread — standard 5C specification
• 1.242 inches-20 external thread — standard 5C specification
• Steel construction for strength and resistance to deformation under clamping load
• Compatible with 5C collet chucks, closers, and indexing fixtures

Compatibility

Designed as a standard 5C-style square collet for use with 5C collet chucks, collet closers, and indexing fixtures that accept the 5C collet form factor.

Installation Notes

5C collets are installed and removed by machinists using the appropriate collet closer or chuck on the machine spindle. Always ensure the machine spindle is fully stopped and the closer is released before inserting or removing a collet. Inspect the collet bore, seating taper, and threads for chips or damage before each use, as debris will affect runout. Do not exceed the rated jaw capacity, as overloading the collet slot can cause permanent deformation.
