Value Collection 3777158 Round Die 1-3/8-6 Unc Hss

Product Description

The VALUE COLLECTION 3777158 is a round threading die designed to cut external threads on rod, bolt stock, and fastener blanks. Made from high-speed steel, it holds cutting edge hardness under the heat generated during threading operations. The die is adjustable, allowing the operator to fine-tune thread fit and compensate for tool wear. It cuts a 1-3/8-6 UNC right-hand thread profile, making it a standard production and repair tool in machine shops, maintenance facilities, and fabrication environments. Machinists, tool-and-die workers, and general maintenance tradespeople are the primary users.

This die is suited for single-point thread cutting applications where a standard unified coarse thread is required. The 1-3/8-inch nominal diameter and 6 threads-per-inch pitch are common in heavy fastener work, structural connections, and industrial equipment repair. Right-hand thread direction matches the overwhelming majority of standard fastener applications. The adjustable design supports use across a range of fits from class 2A to class 3A depending on die setting and workpiece material.

Installation Notes

This die is installed and operated by machinists or maintenance tradespeople using a standard round die stock. Secure the die firmly in the die stock before use and apply appropriate cutting fluid to the workpiece to reduce heat and improve thread finish. Inspect the die for chips or cracks before each use. Follow shop safety practices including securing the workpiece and wearing appropriate eye protection.
