Metric Specialty Threads
Metric Specialty Threads
(OP)
All,
I am looking to find a chart of metric specialty threads. Our design challenge is that we have a thin wall (1.5mm) that we need a 3.5mm clearance home and then we are going to thread this hole to screw a retaining cap in place. If we back off the clear hole to 3.3mm we can then use a standard 4 x 0.7mm thread, but I would like to have a finer thread pitch. Is there anything out there like a 4mm fine pitch thread.
Regards,
Rich.....![[viking2] viking2](https://www.tipmaster.com/images/viking2.gif)

Pick a size ... most are available with taps to suit.

Assuming US take a look at ASME B1.13M-2001 section 7.6.
If it's important enough and/or you're making enough of them special threads are perfectly reasonable. We use them a lot for find adjustment, often parts from Thorlabs or sometimes we have our own made. In inch things like 80 TPI or even 100 TPI are readily available. Try finding the equivalent for metric, the link CBL gives may help.

clk on "Gewinde" and than "Feingewinde" on the left.

Taps here on Pg 66: http://
I looked in Europe and they are available. May be these people can help you: http://mdmetric.com/
