Sutton M4462540 1"-12 UNF Hexagon Die Nut, 52 mm AF - Carbon Alloy Steel
Available
The Sutton M446 is a carbon alloy steel hexagon die nut for cleaning and resizing existing damaged UNF (Unified National Fine) threads. It comes in 16 sizes, 3/16" to 1-1/2", with hex sizes from 18 to 70 mm AF, and can be turned with a wrench or socket where space is limited.
The hexagon die is best suited for maintenance and repair work. Because the die can be used with a wrench or socket, it works in limited space.

Using the die nut
- Clean dirt and rust from the damaged thread before starting.
- Start the die square on the thread, turning forward and backing off regularly to break the chip.
- Use a cutting fluid suited to the material being threaded.
- Die nuts are designed to clean and resize existing threads. For a new thread on plain stock, use a button die from the threading dies and sets range.
- Use for general purpose and DIY threads only.
