CNC Machining Bolts Tolerance

The tolerance requirements for CNC machining bolts can vary depending on the specific application and industry standards. Tolerances refer to the allowable deviation from the desired dimensions of a part. Here are some common tolerance considerations for CNC machining bolts:

1. Diameter tolerance: This refers to the allowable deviation in the bolt’s diameter. It ensures that the bolt fits properly into the corresponding hole or nut. Typical diameter tolerances for CNC machined bolts range from +/- 0.005 to 0.01 inches (0.13 to 0.25 mm).

2. Length tolerance: This specifies the acceptable deviation in the bolt’s overall length. It ensures that the bolt is the correct length for its intended application. Length tolerances for CNC machined bolts can range from +/- 0.01 to 0.05 inches (0.25 to 1.27 mm).

3. Thread tolerance: This relates to the allowable deviation in the thread dimensions, including pitch, major diameter, and minor diameter. It ensures proper engagement with mating threads. Thread tolerances for CNC machined bolts typically adhere to standard thread specifications, such as ANSI B1.1 or ISO 965.

4. Head dimensions tolerance: This specifies the acceptable deviation in the dimensions of the bolt head, such as the head height, head diameter, or head width for hex bolts or socket head cap screws. Head dimension tolerances for CNC machined bolts can range from +/- 0.01 to 0.02 inches (0.25 to 0.5 mm).

5. Surface finish: CNC machining can achieve various surface finishes for bolts, such as smooth, textured, or knurled surfaces. The surface finish tolerance depends on the specific requirements of the application and can range from Ra 16 to Ra 125 microinches (0.4 to 3.2 micrometers).

It is important to note that these tolerance values are general guidelines and may vary based on the specific requirements of the bolt design, application, and industry standards. It is recommended to consult the appropriate standards or work with a CNC machining expert to determine the specific tolerance requirements for your bolts.
