Bolts with 5/32 hex key heads

[tucsonguy]

I'm looking to try to standardize some of my bolts and see if I can find them with 5/32 hex key heads.
Incra on their gauges and sleds etc often use 1/4-20 and 1/4-28 bolts, but all with 3/16 hex key heads.
Does anyone know of a source for these bolts with 5/32 hex key heads?
Thanks in advance...

The sizes have become pretty standard for the key size of cap screws. Not every one of them sticks to the standard but it's kind of a hit and miss thing. They rarely list the key size for a given screw so it can be even harder to find one you want. I would just get used to having another key around. The 1/4" bolts should all use the same size independent of the thread size. Similar subject came up in a bandsaw thread because the keeper screws under the table may have a different size socket.

1/4”-20 screws in both button-head and flat head styles generally use 5/32” hex drives. If you go to McMaster.com and filter for screws that use 5/32” hex drives, you’ll get some 2100 hits in various head styles and thread sizes.

I'm impressed, and feeling stupid for not trying that. McMaster Carr is definitely the best.

5/16-18 set screws and small diameter cap screws also have 5/32 hexsockets. A 4mm hex is essentially the same as 5/32.
