Hi everyone,

I’m working on a project that is using a bolt that is screwed/unscrewed to adjust a part horizontally. The spacing is fairly tight and adjustments would be much easier if I had a turn knob that was above the screw. If you look at the symbols below, the 3 + signs would be the knob. If you’re looking down on the knob from above, it should turn clockwise to tighten the bolt and counter-clockwise to loosen the bolt.

I’ve tried searching online but can’t seem to find anything that would work. Does anyone out there know the name of this type of bolt/setup and where I could buy some?

I’m pretty sure you mean a “hand wheel” or “crank”, right?

From the description, I think the OP wants a knob that is at a right angle to the bolt. If that’s the case, I don’t know of a simple solution. Bevel gears of some sort but how to mount/mate them could be tricky if you’ve got limited space.

Check out Matthias Wendal’s page on making right angle gears. Between the video and the text, you should have a starting point for your mod.

If I’m hearin’ what you’re sayin’, I think MadMark’s post is the closest thing to what you are talking about.

Sorry about the unclear description. I guess I should have drawn a quick sketch in paint. However, with my drawing skills, it may have caused even more confusion.

MadMark and 716 are spot on with what I was referring to. In fact, a guitar tuner with some slight modifications may be the ticket. The bolt I’m using is relatively small (6-32) so I think the size of a guitar tuner would be a good starting point.

Aside from searching for guitar tuners, would the technical name for this be a worm gear? Just trying to determine the best way to search for different sizes.

Thanks again everyone!
