For some reason I cant get the EP fasteners thing to create threads on a curved surface. V-Block Assy(Modified for A2V).skp (3.3 MB) I want an M4 thread through the hole in the holder component 16mm up from the bottom and whenever I do and select thru hole, it doesn’t go all the way through on the…

The most likely reason is scale, working too small. Try scaling up by 10 or 100 and having another go. Edit: I see we have been through all this before with exactly the same thread title.

[image] jayfaas: For some reason Because the EP Fasteners extension works on a single face. Your curved surface is not a single face. Make the screw longer, add a temporary face in front of the curved surface and put the screw on it. Then use Intersect faces and erase the unneeded stuff.

Dave you may well have said all that before in the other thread.

Very possibly. The threads made by this extension are not usable as they are for running a real screw into a hole. I thought the OP had given up on using it in favor of the other options I offered.

So I have heard of this scaling thing before. Do you scale up to say…100, do the work, and then scale down 100? How do you do the correct thread? I always try to do everything to scale so if I scale up 100, does that mean I have to create the M4 thread and include it when I scale?

[image] Doing threads in a thru hole on a curved surface SketchUp I am currently making a cylindrical fixture to spin a stub on a driveshaft and I need to put an M6x1.0 thread through the cylinder as a set screw. I use EP Fasteners and Holes to make the thread but how do …

Working in metric units, I’d scale up by 1000 and set the units to meters. Enter the dimensions as if you were working in millimeters. As I’ve told you at least once before, if you want decent usable threads, don’t use that extension. It doesn’t create usable threads. At least not ones that match t…

Thank you for the help. I really do appreciate it and am sorry that this is a redundant post. I don’t mess with sketchup too much anymore and didn’t think that the last post had any useful information but that was wrong on my part. I will look into the Dave method.
