Cle-line C65148 Round Die 5/16-24 Unf 1 Inch Od Carbon Steel

Product Description

The CLE-LINE C65148 is a round threading die designed for cutting external threads on rod, bolt stock, and fastener blanks. It cuts a 5/16-24 UNF right-hand thread profile and features an adjustable design that allows the technician to fine-tune the thread fit by varying the die opening. The 1-inch outside diameter fits standard round die stocks and holders. At 3/8 inch thick, the die provides adequate chip clearance and cutting depth for clean thread formation. Carbon steel construction delivers the hardness needed for threading mild steel, aluminum, brass, and similar workpiece materials.

This die is suited for maintenance, repair, and fabrication work where UNF fine-thread fasteners are required. Typical applications include threading replacement studs, repair bolts, and custom-length fasteners in light industrial, automotive, plumbing, and HVAC service environments. The 5/16-24 UNF specification is commonly encountered in instrument fittings, small-diameter hydraulic connections, and precision mechanical assemblies. It is used by machinists, pipefitters, maintenance technicians, and field service professionals who need to chase or cut new threads on site or at the bench.

Key Features

• 5/16-24 UNF right-hand thread profile for fine-thread fastener applications
• Adjustable die opening allows thread fit tuning without changing tooling
• 1-inch OD fits standard round die stocks and holders
• 3/8-inch thickness provides chip clearance for clean thread cutting
• Carbon steel construction handles mild steel, aluminum, and brass workpieces
• Series 0610 designation for straightforward replacement and reorder

Compatibility

Designed for use in standard 1-inch round die stocks. Fits Series 0610 tooling. Verify die stock accepts 1-inch OD round dies before installation.

Installation Notes

Secure the die firmly in the die stock before beginning thread cutting. Apply cutting oil to the workpiece to reduce friction, extend die life, and produce cleaner threads. Always back off the die periodically to clear chips when cutting longer thread lengths. The adjustable screw on the die should be set before cutting begins and rechecked between passes if thread fit needs correction.
