Forged Nuts
Atlanta Rod precision domestic forged nuts from 3/8” up to 4” and metric equivalents in diameter to customer specifications. We can manufacture domestic nuts in the types, grades, and materials listed below, and alongside our full line of anchor bolts and headed bolts.
Depending on the specification, we can provide material in a plain (non-coated) state, hot-dipped galvanized, zinc plated, or any other special plating your project might require. And all manufacturing adheres to ASTM specifications, with domestic certifications of melt and manufacture available.

Hex/Finished
A hex or finished hex nut is one of the commonly used types of nut. We manufacture to ASTM A563 specifications in the diameters of 3/8” to 2-¾” and metric equivalents. Finished hex nuts are compatible with the following ASTM specifications: A307, A354, A449, and F1554.
See the following charts for specifics: Finished Hex Nut Dimensions and Nut Compatibility Chart
Heavy Hex
Heavy hex nuts have a washer face and are thicker and larger than finished hex nuts. Typically, heavy hex nuts are used with higher strength and larger diameter bolts. We manufacture heavy hex nuts to ASTM 563 and A194 specifications in diameters of 3/8” to 4” and metric equivalents.

Hex Coupling
A coupling nut is a hexagonal shaped nut used to join two threaded rods. Typically, the thread pattern is the same throughout the nut, unlike a turnbuckle that has opposite thread patterns on each end.
Jam
Jam nuts are very similar to standard hex or heavy hex nuts with the exception that they are approximately half as tall. Typically, jam nuts are used to prevent loosening of another nut by “jamming” against it or when a standard nut won’t fit in the application. Jam nuts can be manufactured in a hex / finished or heavy hex pattern. We manufacture jam nuts in diameters of 1/2” to 4” and metric equivalents.
Lock
A lock nut is a type of nut used to prevent loosening under extreme torque or vibration. Lock nuts can be manufactured in a hex / finished or heavy hex pattern and can be self-locking with a pin that prevents the nut from backing up the threads or use a nylon ring that grips the threads to lock the nut in place. We manufacture lock nuts in diameters of 1/2” to 4” and metric equivalents.
Custom
We can custom manufacture many special nut types. If you are looking for something unique or not previously mentioned, please be in touch with our sales team.
