thread

I have a set of 4 metric (I believe) bolts that have stripped the threads out of a diesel engine thermostat housing they were bolted into. The reason for the stripping was because the previous owner had used the wrong threaded replacement bolts which ruined the threads so it is not a mechanical...

Does writing software count as a "Project"? Well if it does I would like to tell you about a program I wrote for lathe users. RideTheGearTrain.com It was designed to tell you how to set up the gear train to cut any thread. When it runs it usually gives you a long list of different ways you...

I had to buy a new faucet aerator for my kitchen and went to Home Depot. I bought and installed it without issue. But, what is up with these threads?!? What oddball sizes! Does anyone know the origin of these weird threads? Dual thread 15/16 in. - 27 and 55/64 in. - 27

So, I plan on cutting my first thread on my mini-lathe and I'm looking for some info. I'm making a captured nut puzzle with a 5/8"-11 thread and I'm trying to determine the depth of cut. Since the thread in the middle of the work piece, I can't keep trying a nut to see when the depth is...

Could anyone help me with identifying the tap size and drill size for this thread? I'm trying to thread this fitting into a tank and need to know what tap to order. Let me know if you need more information! Thanks in advance, Andrew

Hello hobby machinists! I've been making changewheel charts, skip the next two paragraphs if that's all you're interested in. I want to cut a 2BA thread on my ML7 because I'm finding the allen bolt which is used to engage and disengage the back-gear is turning out to be a nightmare to reach...

Hi, The video shows you how to determine the parameters of external and internal metric threads. For measuring the pitch different methods with and without a thread gauge are demonstrated. The video has a German soundtrack but English subtitles are added to YouTube. If you don't see them by...
