Value Collection 315-1413 Round Die 1-1/16-16 Hss Adjustable

Product Description

The VALUE COLLECTION 315-1413 is a round threading die machined from high-speed steel (HSS) for cutting external threads on rod, pipe, and fastener stock. Designed for 1-1/16-16 thread size following the UNS (Unified National Special) standard, it cuts right-hand threads and includes an adjustable split for fine-tuning thread fit and die tension. At 0.5 pounds, it seats in a standard round die stock holder and is used by machinists, pipefitters, maintenance mechanics, and toolroom technicians who need precise, repeatable external threads in production or repair work.

This die is suited for threading 1-1/16-inch diameter stock at 16 threads per inch to the UNS standard. Typical applications include fabricating threaded rod ends, recutting damaged threads on mechanical assemblies, and creating custom fastener threads where standard UNC or UNF pitches do not apply. The adjustable design allows the operator to take a roughing pass and a finishing pass with the same die, producing a cleaner thread form with less tool stress on harder materials.

Key Features

• High-speed steel construction for durability across ferrous and non-ferrous stock materials
• 1-1/16-16 UNS thread specification for non-standard pitch applications
• Adjustable split design allows thread-fit fine-tuning and multi-pass cutting
• Right-hand thread direction — standard orientation for most mechanical assemblies
• Compatible with standard round die stock holders sized for this die diameter

Compatibility

Designed for use with standard round die stock holders that accept dies of this diameter. Intended for cutting 1-1/16-16 UNS right-hand external threads on compatible stock materials.

Installation Notes

Round dies are installed by a machinist or skilled tradesperson into a matching round die stock holder secured with set screws. Before use, ensure the workpiece is properly chucked or held in a vise and that cutting oil or thread-cutting lubricant is applied to reduce heat and extend die life. Set the adjustable split to the wider opening for a roughing pass, then tighten incrementally for the finishing pass. Inspect the die for chipping or wear before each use, as a damaged cutting edge will produce out-of-tolerance threads.
