Value Collection 315-1141 Round Die 3/8-18 1 in Od Hss

Product Description

The VALUE COLLECTION 315-1141 is a round threading die designed to cut external threads on rod, bolt blanks, and round stock. Sized at 3/8-18 with a 1 inch outside diameter, this die produces right-hand UNS threads in a single setup. The die body is machined from high-speed steel (HSS), which holds a cutting edge through repeated use across a range of materials. An adjustable design allows the operator to dial in thread fit by opening or closing the die slightly using a set screw on the die stock. Licensed machinists, plumbers, and pipefitters are the typical users for this class of tooling.

This die is suited for threading work in shop environments and field repair applications where 3/8-18 external threads are required. Common uses include fabricating threaded studs, repairing damaged thread ends, and producing custom-length threaded fasteners. The 1 inch OD fits standard round die stocks designed for that holder diameter. Right-hand thread direction is the conventional standard for the vast majority of mechanical fastener applications.

Key Features

• 3/8-18 thread size in UNS thread standard
• 1 inch outside diameter fits standard round die stocks
• High-speed steel construction for durability and edge retention
• Adjustable body allows fine-tuning of thread fit and tolerance
• Right-hand thread direction for standard fastener applications

Compatibility

Designed for use in standard round die stocks that accept a 1 inch OD die. Suitable for cutting 3/8-18 UNS right-hand external threads on compatible rod and stock materials.

Installation Notes

Seat the die squarely in the die stock and secure the holding screws before beginning any threading pass. Apply cutting oil to the workpiece and die throughout the threading operation to reduce heat and extend tool life. Use the adjusting screw to open the die for a roughing pass and close it for a finishing pass when close thread tolerances are required. Inspect threads with a ring gauge after cutting to confirm proper fit before assembly.
