i've got a bell and carlson stock i like (https://www.bellandcarlson.com/index.cfm?fuseaction=category.display&category_ID=1053) but the problem is it's got hex or allen key bolts holding the cheek piece in place and if the cheekpiece is up, i cannot remove the bolt. in order to adjust the cheekpiece i'd have to use an allen key, any recommendations for a different type fastener that could be adjusted without a tool? like a thumbscrew?

You need to figure out the thread size and pitch then buy some sort of threaded knob with the same exact thread.

We can't help you with that
 
thanks guys, i should have been more clear.

it's not just the pitch of the thumb screws (the bolts are 1/4-20). this specific stock has tapered bushings that are locked in place with the flat head cap screw that i want to replace. i was thinking about 3d printing a tapered piece to replace the taper of the cap screw, but it occurred to me i could possibly just get a different bushing that's taller so it sticks out .125 proud of the hole then a typical thumb screw from McMaster would lock it into place

my question was really if anyone had already done anything like this so i didn't reinvent the wheel
 
After clicking on the link to the model of stock you have, I understand your issue now. I had one of those stocks several years ago, and yes, the tapered bushing method of locking the cheekpiece height is different than their newer stocks. But I sold that stock probably 10yrs ago, and don't recall much about its hardware.

no worries.
i'll likely order some knobs from McMaster and model the tapered bushing i need in Fusion360 then 3d print it
 
I ended up 3d printing these knobs and used some nuts as spacers
Works quite well actually
