Not all companies need to source their UN thread tap or their metric thread tap in bulk quantities. If you are in need of custom thread taps but you want them in low volumes then finding the right suppliers could be a bit challenging. If it is standard thread taps you will be able to order any number of thread taps regardless of whether it is just a single unit or hundreds of units. However, that is not the case with custom thread taps.
If it is custom metric tap or UN thread tap, the manufacturer needs to set up the dies and go through a long setting up process. After such a long set up process if all that you are going to require is just a small number of thread taps then they will not make any profit out of your order. So, most manufacturers deal either with standard thread taps or with high volume custom thread taps.
Finding a custom thread manufacturer could be a difficult process if you want to place low volume orders but it does not mean that you will never find such suppliers. You will definitely find such suppliers but with a bit of a search. In case you are not able to find a local supplier you can check with manufacturers in China. There are a number of manufacturers that are ready to process even a single piece order. It is up to you to invest enough time to spot them. Take your time to review and screen your manufacturers that are ready to process low volume orders.
What you need to understand here is that your current order may be a low volume order but you could be a regular customer to the manufacturer because thread taps break frequently. Some of the manufacturers see your business as a long term business. By providing you with what you need even if it is a low volume order, your manufacturer is counting on your future, long term business. As they would have already cut the die for the custom dimensions you need all the future orders would be as good as standard thread tap orders.
Do not forget to compare the prices if you are ordering your thread taps from a manufacturer directly. Just because you have found someone ready to meet your low volume order you should not blindly go with the first manufacture that you come across. If you do, then you are likely to pay more than what you should on your thread taps. With so many reliable companies in the industry you will definitely be able to find a manufacturer that is ready to meet your diverse requirements. Find companies that you will be able to work with on a long term basis so that you could cut the long and tedious sourcing process if you always order your thread taps in low volumes. Enjoy considerable savings by sourcing your thread taps from China.
