I'm sure most of you have seen one of these speeders that were designed to hold a bolt and spin the nut at the same time though you probably didn't see it in this brand....Anyway, I usually run into them in 9/16" crankcase? or 1/2". This one is 15/16". Any ideas about what it could be used for? ie. 15/16" nut and bolts that a tool like this could reach and the nut and bolt head are no more than 2 1/2" apart which is as wide as the extension piece will spread? Even ruling out the Model T or A is still progress on finding an answer. thanks.

For Model T use, you can run down the crankcase nuts and bolts with it. I assume on the Model A as well

Hi. 15/16? Thanks.

Let me rephrase that....I'm not asking what these kinds of tools are normally for, and in my original post I mentioned the crankcase and 9/16". There was a 1/2" size, apparently for rear axle work too. I've seen these by Blackhawk and Walden Worcester and probably others too. The issue with this particular tool is the size. The sockets are 15/16". I'm asking if anyone here has a theory about ( keeping in mind that 15/16" size) what it's specific use might be. I've never seen another one of these in any size by P&C tools, it might have some obvious application on another 20's vehicle not necessarily a Ford, or for all I know it could just be something they were thinking about marketing, and decided not to, when Walden sued Blackhawk over the design. Thanks.

These tools are shown in a couple of the Murray Fahnestock books, so they were used somewhere. He specifically shows them used on Model Ts

Right. The 9/16" and 1/2" sizes of this style tool were marketed for the Model T originally, that's where I started from.

Many large oil or water pipes are connected with flanges with 8, 12, 16, or more bolts. This could have been used to run these bolts down before the final torque was applied. 15/16 nut and bolt head is 5/8 bolt.

I'm not where I can check, but are the body to frame bolts 15/16 wrench size. ??

...also spark plugs....

Thanks. I'll have to follow up on this.

The only ¹⁵⁄₁₆ I can think of are drain plugs, rear wheel nuts, and (I think) under-axle wishbone nuts. None of them have bolts.

appreciate it.

The body bolts I believe are 11/16 or 3/4 hex. With the splash aprons and rear leaf spring being in the way I doubt this would be very useful on the body bolts even if it were the correct size.

Thanks for taking into account not just the size, but the purpose/ limitations of the tool design. That's what it's going to take to figure it out eventually.
