When setting up your design for tapping, make sure that the holes are no larger than 4.00″. We’ll resize them automatically when you choose a tap size before checkout. Reference this helpful drill and tap size chart to see the hole size we’ll use.
Ensure tapped holes are the required distance away from adjacent cut features. See our guidance on feature distances in the Tapping Guidelines.
Design all tapped holes to be directly perpendicular to the main surface. We do not offer tapping at an angle. Ensure that your overall flat part size meets our size requirements for tapping.
Keep in mind that available tap sizes will vary by the material and thickness you choose. You can confirm which tap sizes are available for each material thickness on our processing limits page.
