Such as: diameter, pitch, series, material, etc. The following are some commonly used standards:

1. a193 b7 threaded rod ACME thread: American Society of Mechanical Engineers (ASME) standard, commonly used in sliding, rotating, stopping and feeding applications. Its pitch angle is 29 degrees, and the accuracy levels are G1, G2, G3, G4, among which G1 level has the highest accuracy, with an error of 0.025mm/m.

2. Trapezoidal thread a307 threaded rod: commonly used in various mechanical transmission devices, such as torque devices, lifting equipment, mold machinery, etc. Its pitch angle is 30 degrees and its accuracy level is the same as ACME thread.

3. Unified threaded rod: It is a standard developed by the American Mechanical Standards Institute (ANSI) threaded rod and is widely used in machine tools, automobiles, bicycles, construction and aviation parts.
