Manufacturing Method & Tolerances
Manufacturing Method:
U-bolts are formed by cold or hot bending steel rods into a U shape (round or square). The legs are threaded using CNC threading machines. Available in single or bulk production, with optional coatings and assembly with accessories.
Tolerances:
- Threading: As per IS 1363 / DIN 976 / ASTM A307
- Dimensional: ±1mm unless specified
- Custom tolerances accepted for drawing-based orders
Applications & Usage
- Used in supporting pipe systems in foundations
- Suitable for poles, towers, and steel brackets
- Ideal for securing machinery to concrete bases
- Common in telecom, electrical, and mechanical setups
- Applicable in bridges, structural supports, and substation foundations
