Tapping & Threading FAQs

What hole sizes can you thread?

We support threading operations from #0 up to 2" diameters, depending on the job’s material and whether it’s fulfilled internally or by our partners.

Do you offer blind hole threading?

Yes. We perform blind and through-hole threading with tight control over depth and pitch quality.

Is this work done in-house?

Some threading and tapping jobs are completed at our facility in Ontario, while others are handled through our Canadian supplier network based on complexity or timeline.
