Topic tags/keywords: question metric bolts adjustable handle knob

There is a slight mis-alignment in the upper guide assembly on my Grizzly bandsaw. Unfortunately, Grizzly uses metric. Instead of trying to find and use an allen wench every time I raise or lower the upper guide to reposition the side bearings, I am considering replacing the allen cap screws with an adjustable handle knob (picture below). Where can I find a supplier of these?

Look here on McMaster-Carr. On the left you can select the metric thread size you need.

I second McMaster-Carr. The nut-gripping part on one of these on the tool rest on my cheap Harbor Freight lathe wore out really fast, so I replaced all of them at once w/metal ones from McMaster. Granted, it’s just pot metal, but they still beat plastic.

I bought mine at WoodCraft. I bought the larger size, cut the thread off, re-tapped to my desired threading and used a piece of “all-thread” to complete these adjustable bolts. This was one of the first upgrades I did for my astronomical telescope mount, in order to eliminate the “Allen screw” syndrome that you mention:

Buy HERE

(Below) Tool-less RA & DEC Adjusting Clutch Levers and Thumbscrews – I found the adjustable levers at a WoodCraft Store but they only came in either 1/4-20 coarse thread (too small to drill out and re-tap) or 5/16” threads (got these because they allow for re-tapping) so a good friend tapped and drilled the 5/16” bolt heads on the lever to the required 1/4-28 fine thread pitch and added the all-thread. Spacers are required to miss the RA housing and should be 5/8” long but still leaving 1.5” of threaded bolt on the end.
