Tapped Hole Identification and Selectable Sizes

Inch Thickness Gauge Standard

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.

  • To aid correct identification of tapped holes, it is recommend that you specify the CAD package you normally use in “Automatic Hole Type Recognition.”
  • Hole diameters detected by the meviy platform will then be checked against the hole diameters for the specified CAD package (Table 2).
  • *The link below provides more information on configuring settings.

*2 When the SOLIDWORKS hole option selected is “Remove threads.”

Tapped Hole Size Selection

Tapped holes cannot be selected for perforated metals, shim plate materials (Cold Rolled Low Carbon Steel (for Shims) or 304 Stainless Steel (H) (for Shims)) or clear resin.

Available tap sizes are grouped by material and may not be available for all material types listed.

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.

  • To aid correct identification of tapped holes, it is recommend that you specify the CAD package you normally use in “Automatic Hole Type Recognition.”
  • Hole diameters detected by the meviy platform will then be checked against the hole diameters for the specified CAD package (Table 2).
