Precision tapping is thread work held to the print, and it is often the difference between a fabricated part that bolts up and one that has to be made again.
Threads are where a lot of otherwise good parts get thrown away. A hole drilled slightly off, a tap started out of square, a thread stripped by an impact gun on the last install. None of those are dramatic failures and all of them stop an assembly.
We tap and thread in aluminum, steel and stainless, on parts we fabricate and on parts you bring us. We also do the repair side, which is often the more urgent call: a stripped thread in a casting that cannot be replaced, a broken tap that has to come out without damaging the part around it.
The reason to keep this in the same shop as the fabrication is that the part usually needs both. A bracket that gets cut, welded and then tapped in three places has been handled once instead of shipped twice.
Send the print if you have one. Thread work is specified by the drawing, and quoting from a description rather than a print is how the wrong thread ends up in the right hole. Where there is no drawing, send the part itself along with the fastener that has to go into it.
This work runs alongside the rest of the shop rather than separately from it. A bracket that gets cut, welded, blasted and tapped is one job here, handled once. That is usually both faster and cheaper than moving a part between two or three suppliers, and it means there is one company answering for whether the finished part is right.
How this job runs
The same sequence every time, so you know what you are buying.
Threads cut to the print in aluminum, steel and stainless.
Holes, faces and features machined on parts we build or parts you send.
Stripped and damaged threads recovered in parts that are not worth replacing.
Work done against the print you supply, rather than against an assumption about what will probably fit.
Most parts do not fail at the weld. They fail at the hole.
Thread and hole work is unglamorous and it is where fit-up problems actually live.
Questions about precision tapping and machining
Can you tap parts we bring in, or only parts you make?
Both. Send the part and the print and we will quote the thread work on its own.
Can you recover a stripped or damaged thread?
Often yes, and it is a common call on castings and housings that are expensive or no longer available.
What materials can you thread?
Aluminum, steel and stainless.
Do you need a drawing?
For precision work, yes, a print is the right way to specify it. For simpler thread repair, the part itself is usually enough.

Describe what you need made or fixed and we will send a quote back. Photographs and drawings help more than anything else, so the form takes uploads.
Commercial and industrial work. Residential is limited to handrails, gates and fences, and we do not take small repairs.
