Need to confirm a bolt head size
 

I'm working on my 782's front grill and I need to remove the 4 12 point bolts that hold it to each side of the front frame at the bottom. I think I need a 9/32" 12 point. Can anyone confirm so that I can order the correct socket?

thanks

I just checked mine and the grill housing (tag 1 in the illustration) is held on by four six-point 5/16" bolts and a 1/2" deep socket is needed to take them off.

from the looks of it, I think it's a 12 point bolt.
They all appear to be original, so maybe IH changed things up at some point.

According to the Parts Manuals, both the on line version as well as the paper version, Plus both IH & CCC productions....they used 710-0376 bolt. It is a standard Hex Head Bolt, 5/16-18 x 1", grade 5.

I find NOTHING with any reference to a 12 point bolt head.

Good info. It seemed like an odd thing for IH to do and after many years of wrenching on old IH stuff, it's the first time I've ever encountered a 12 point bolt on one. I bought a cheap "spline socket" set at Auto Zone and the bolts came right out. Thanks

i have also seen those bolts in the same place on the 82 series and later tractors joe allen

me too on the 782 IH built.

I too have seen 12pt head bolts there. They are 3/8" 12pt.

they take a 5/16" 12 point socket

Yes, just a regular 12 point socket normally used on hex heads.
