Tapped Hole Identification and Selectable Sizes

Tapped Hole Identification

  • Hole diameter information in meviy’s hole information database is registered corresponding to the nominal diameters of tapped holes from each uploadable file extension. Detected hole diameters are checked against the table below (Table 1).
  • *If the detected diameter does not match any entry in the table, the hole will be treated as a through hole. However, you can change the hole type or nominal diameter when configuring the quote settings.
  • *If a diameter corresponds to multiple nominal diameters (below, 5.00 mm), the larger nominal diameter (M6) will be prioritized and selected.

Tapped Hole Size Selection

Tapped holes cannot be selected for perforated metals, shim plate materials (SPCC [for shims] or SUS304(H) [for shims]) or clear resin.
