Quick release bolting
Quick release bolting
(OP)
I have a studded access door that requires unbolting for inspection. Besides replacing the door with something different (hinged etc) does anyone know if there's such a thing as a quick release nut that will use regular coarse thread.

RE: Quick release bolting
Thirty years ago, I had an Australian Repco cylinder head reconditioning machine that had quick release hex nuts on its fixturing. These had a slanted clearance hole like those in ajack1's link above. They worked well, but they felt a bit spongy and tended to deflect the stud at the outer end due to the one sided thread, I would be reluctant to really torque them down.
There is a design of nut that avoids this problem and looks a lot stronger, although I've not had any occasion to try them and they're probably a lot more expensive.

SinoTC - thanks - that's just the sort of thing I was looking for. Very interesting design.

Hello Pulpeng,
It's a relatively costly option but, have you considered Hydraulic Nuts?
Actual "tightening" and "untightening" is the biggest user of time in any such process - even with slip-on nuts as described above.
Hydraulic Nuts replace standard hex nuts. Once they're all spun down, they're connected in parallel to a common pump. This pump applies pressure to simultaneously stretch each nut. When the required preload has been applied (usually in mere seconds), one simply turns down a locking collar which retains the load. Dissassembly works in reverse: The quick-connect harness is attached, pressure is applied, the locking collars are turned back, the harness is removed and, the nuts are spun off.
Not only is this a "quick" process, it also results in a known applied load providing even gasket compression

Hex slip-on nut is possibly what you are looking for.
