13 best hex threading dies
Hex threading dies are cutting tools used in industrial applications for creating external threads on cylindrical surfaces, specifically hexagonal shapes. These dies are a crucial component in the process of threading, which involves cutting or forming threads on a workpiece. Threading dies come in various shapes and sizes to accommodate different threading requirements, and hex threading dies are designed for producing hexagonal threads.
Here are some key points about hex threading dies:
Material and Construction: Hex threading dies are typically made from high-speed steel (HSS) or other durable materials. The choice of material depends on factors such as the type of material being threaded and the volume of work. High-quality construction ensures longevity and precision in the threading process.
Hexagonal Threads: Unlike traditional round threads, hex threading dies are specifically designed to create hexagonal threads on the external surface of a cylindrical workpiece. Hex threads are commonly used in applications where a hexagonal shape is desirable for better grip or specific functional requirements.
Usage: Hex threading dies are employed in various industries, including manufacturing, construction, and automotive, where hexagonal threads are needed.These dies can be used with different threading tools such as die stocks or threading machines.
Sizes and Pitches: Hex threading dies are available in various sizes and pitches to accommodate different thread specifications. The size of the die corresponds to the diameter of the workpiece, while the pitch refers to the distance between individual threads. Users must select the appropriate die size and pitch based on their threading requirements.
Cutting Process: Threading dies, including hex threading dies, work by removing material from the external surface of a cylindrical workpiece to create threads. The die is rotated around the workpiece, and as it makes contact, it cuts into the material, forming the desired thread pattern.
Precision and Quality: The precision of hex threading dies is crucial to ensure accurate and consistent thread profiles. High-quality dies help achieve clean and well-defined hexagonal threads, contributing to the overall quality and functionality of the threaded product.
Maintenance: Proper maintenance of hex threading dies is essential for extending their lifespan and ensuring optimal performance. Regular cleaning, lubrication, and inspection help prevent wear and maintain cutting edges in good condition.
In summary, hex threading dies are cutting tools designed for creating hexagonal threads on cylindrical workpieces. They play a vital role in various industries where hex threads are required for specific applications, and their quality and precision are critical for producing accurate and reliable threaded products.

User questions & answers
| Question: | does the 1-11-1/2 work for American Pipe Threads, and is it for 1" pipes |
| Answer: | Yes, this is a die for NPT (National Pipe Thread). It will thread 1 inch pipe with threads that are 11 1/2 TPI (Threads Per Inch). NOTE: this is for dressing up threads or rethreading a pipe. It is NOT for making new threads. For cutting new threads you will need something more durable than carbon steel. |
| Question: | Is 1/8" the inner diameter of the pipe, meaning this will thread pipe with an outer diameter of |
| Answer: | This die is meant to thread 1/8" Nominal Pipe Size (NPS) pipe. The outer diameter is about 0.41". The inner diameter depends on the wall thickness but the most commonly found type, Schedule 40, that you'll find on the shelves in big box stores, has an inner diameter of about 0.27".Jay is correct that if you thread 1/8" NPS pipe with this die, it will connect to other 1/8" fittings. |
| Question: | What size is the die - what is the distance across the flats |
| Answer: | 2-1/8" ACROSS THE FLAT |
| Question: | Will this work on aluminum pipe |

User questions & answers
| Question: | Will this hold a hexagonal die that measures .685" measured flat to opposite flat side |
| Answer: | No, it is made for dies that measure 1.0" across. I just looked at mine and .685 is too small and would not work, the set screw isn't long enough to try to secure a die that small, and even if it was there would be no way to center it in the tool. Are you sure it isn't 5/8" (.625) across? If so the HANSON 12457 should work, or any other 5/8 hex die stock. |
| Question: | What's it made out of? Steel, aluminum, or zinc |
| Answer: | It is made of steel. |
| Question: | How do you use a tap in this tool what do i need to buy in order to do so |
| Answer: | THIS TOOL IS USED FOR DIES BUT CAN BE USED FOR TAPS WITH A SPECIAL INSERT THAT HAS THE SMALL SQUARE HOLES TO PUT THE END OF THE TAP INTO BUT I DON'T KNOW THE NAME OF THE INSERT. IT IS EASER TO USE A T-HANDLE FOR TAPS, THEY HAVE THE RIGHT SIZE HANDLE SO NOT TO SNAP THE TAP OFF IN THE HOLE. |
| Question: | I am confused. is this for hexagon 1" dies or is it for round dies |
| Answer: | This is a hex head die that works with both. The set screw is positioned to hold a round in place. |
