Snap On L-710 Ratchet strange hex key use

[3baygarage]

Found this L-710 today at a sale. It looks similar to a Hi-Lok style ratchet but there is no drive square.

That's a 3/8" allen wrench running through it. Held with a set screw. The gear was forged or machined this way as one piece.

Whatever this is for it looks like it was used in a harsh environment.

A strange one to be sure! If by a Hi-Lo you mean one of these;I was told this was originally designed for front end work.It is a 7/8ths 12 point with a 1/2 inch square drive adaptor in place. I bought it to use on my lug bolts.Couldn't pass it up for the price($15)

^That's one of a variety of vehicle alignment ratcheting wrenches they made.^ They came with various sockets for doing that work. But sure they can be of good use anywhere.

A Hi-lok is a regular looking ratchet with a hole through the center of the drive square for an allen wrench. They are used mainly in the aircraft industry I believe. I'm wondering if my ratchet was as well, although I've never seen one that couldn't hold a socket too.

That is a odd one, have not seen it.

Looks like a jig to break loose a stuck fastener and then be able to spin it off quick with the L-handle. Then quickly run it up when installing by hand before tightening it with the ratchet.
