Threaded Holes Guidelines

Use a modeled thread feature when your part needs a repeatable fastening location. The quoting workflow can identify common thread geometry and flag details that need review before machining begins.

For drawing-based work, include the desired size, depth, and any special requirements so the manufacturing review can confirm the intended feature.

Milled vs. Turned Parts

Thread selection depends on part geometry, tool access, material, and the operation that creates the surrounding feature. A clear model helps align the selected operation with the design intent.

For both approaches, define the nominal diameter, pitch, depth, and any counterbore or relief needed around the feature. These details keep the machining review decisive before production begins.

Plan the thread against the available wall thickness and the surrounding shoulders so the selected tool can reach the intended depth. Blind features also need practical runout space at their base.

Threading Considerations

  • Check whether the feature is through, blind, or interrupted before requesting a quote.
  • Leave accessible space for the selected thread depth and tool approach.
  • Identify left-hand features, unusual pitches, or special fit classes directly on the drawing.
  • Keep nearby walls and shoulders clear of the planned tool path.
  • Include the mating component when an assembly requirement governs the thread choice.
