Large Diameter Threading
Top Rated Anchor Bolt & Treaded Rod Manufacturer in Phoenix, Arizona
Large Diameter Threading Capabilities
Halo Structural Products provides large diameter threading services for anchor bolts, double end studs, and structural-grade all thread rod. We manufacture threaded products in diameters ranging from 1/2″ through 4″, utilizing rolled threads through 2-1/4″ diameter and cut threads for larger diameters.
Our equipment is configured to produce high-quality threads on a wide range of material grades, including ASTM F1554 Grade 55, ASTM F1554 Grade 105, ASTM A193 Grade B7, ASTM A354 Grade BC, ASTM A354 Grade BD, and other commonly specified anchor bolt materials.
Assembly Capabilities
We utilize multiple threading processes depending on diameter, material grade, and application requirements.
Cut Threading
For diameters larger than 2-1/4″, Halo provides precision cut threading.
Cut threading is commonly used for:
- Large diameter anchor bolts
- Large diameter double end studs
- Large diameter threaded rod
- Specialty material grades
- Custom thread lengths
Halo can manufacture cut-thread products up to 4″ diameter, allowing us to support heavy civil, utility, bridge, industrial, and structural steel projects that require oversized threaded components.
Thread Rolling
For diameters up to 2-1/4″, Halo primarily utilizes thread rolling. Thread rolling displaces material rather than removing it, producing threads with excellent strength, surface finish, and dimensional consistency.
Benefits of rolled threads include:
- Improved fatigue resistance
- Increased thread strength
- Superior surface finish
- Consistent fit with mating hardware
- Efficient production for large quantities
Equipment
Our threading equipment lineup includes:
- Die head threading machines for flexible production and custom thread lengths
- Diameter-dedicated two-die through-feed thread rolling machines for high-volume manufacturing
- Large-capacity equipment capable of processing heavy structural fastener products
This combination of equipment allows us to efficiently manufacture both small custom runs and large production orders.

- Straight anchor bolts
- Bent anchor bolts
