Other than weird, one off applications we are totally standardised on allen head bolts (1/4-20 and 10-32) mostly socket head, with button head where we need the low profile. This year we have 4 3/8 hex bolts as arm stops, and 16 3/8 hex bolts in our elevator. Everything else is allen head. We use “allen key” tools a lot!
Other than in weird confined spaces where you only can snake an allen key in, leave your standard allen keys in the drawer and use either T-Handle or screwdriver handled allens. Way faster, easier to use, easier to apply higher torque, and have greater reach. Get a ball end set for off axis work and a set of straight cut ends for when you need to hold an allen bolt straight as you stick it through a gearbox or inside of a box section. So far this year, I have not picked up a standard allen key.
I have not tried the ones you mentioned so I cannot prove you are wrong (can think it, just can’t prove it) but we are very very happy with Bondhus. Great machining, very strong, and they have a true lifetime warranty. They are also made in the USA, if that matters to you.
They certainly are not the cheapest, but once you experience the joys of removing a shaft collar with a cammed out setscrew you become a believer in better tools.
Their long shaft T Handle ball end allen keys are the go to in our shop. The screwdriver versions are also very good, and faster to use when you don’t need the higher torque application.
The other allen variant that is most wonderful is the micro ratchet and 1/4" insert bit style. We use both Wera and Wiha micro ratchets with various hex insert bits. I like the Wera ratchets slightly more.
Much more comfortable than a standard allen key, stronger, ratcheting, and can get into almost every place that you can get a standard allen key. With a fine tooth ratchet you can tighten down a fastener in a very confined space, without having to go through the hassle of turn, remove, fight to get back on the head of the fastener, turn… Add in ball end insert bits for some off axis action and life is much better. One of the issues with standard allen keys is that most only have ball end available on the long end.
We also use insert bits in 12V Dewalt drivers for disassembly work (like removing skid plates). Tend not to use them for assembly as “tighter is gooder” seems to be a mantra that many of our students are fully committed to.
