Value Collection 81942333 Round Die 3/8-32 1 in Od Hss Left Hand

Product Description

The VALUE COLLECTION 81942333 is a round threading die designed to cut external left-hand threads in a 3/8-32 UNEF thread specification. Manufactured from high-speed steel (HSS), it delivers the hardness and heat resistance required for threading operations on ferrous and non-ferrous metals. The die measures 1 inch in outside diameter and features an adjustable design that allows the operator to fine-tune thread fit by controlling cutting depth. It is used by machinists, maintenance technicians, and trade professionals who need to produce or restore left-hand threaded fastener profiles on bolts, studs, and shafts.

This die is suited for both production and repair threading tasks in machine shops, maintenance facilities, and industrial job sites. Its left-hand thread direction makes it specifically applicable where standard right-hand threads are not appropriate, such as on components that experience counter-clockwise rotational loads. The adjustable feature accommodates minor variations in stock diameter and allows for multiple passes to achieve a clean, accurate thread form.

Key Features

• Left-hand thread direction for applications requiring reverse-thread fasteners
• High-speed steel construction for durability and resistance to heat generated during cutting
• Adjustable design allows thread depth fine-tuning for precise fit
• 1 inch outside diameter fits standard round die stocks and holders
• UNEF thread standard for fine-pitch threading at 3/8-32

Compatibility

Designed for use in standard 1 inch round die stocks and holders compatible with round adjustable threading dies.

Installation Notes

Threading dies are installed and operated by machinists and maintenance technicians using a compatible round die stock. Secure the workpiece firmly before beginning the threading operation and apply appropriate cutting fluid to extend die life and improve thread quality. Inspect the die for wear or chipping before each use. Follow applicable workplace safety standards when operating cutting tools.
