you'll need an 8-pt 5/16 socket to adjust the bands on a torqueflight.

Square nuts have also been known as plow nuts. A lot of the older farm impliments were put together using square nuts. A cresent wrench or 'water pump' pliers do not slip off a squre nut like they do a hex. All a farmer needed for repairs in the field was a couple of cresent wrenchs, a hammer and some pliers. The reason they have mostly disappeared is it takes more steel to make a square nut than an equall size hex nut.

That is so cool, Cec! The sqare-headed bolts were called stove bolts. I am not sure why Chivvies are called 'Stovebolts'.

It was explained to me that the old inline motors that used the square headed bolts were called 'stovebolts' after the square bolts used on the old wood burnig stoves. I don't know when the motors stopped using square bolts but I've heard the 216,235 and 261 Chevys called 'stovebolts'.
Did the old steam locomotives also use square head bolts?

i helped a buddy of mine swap a '58 model 235 six for the tired 216 in his '50 chevy a while back and he told me they were called stovebolts because of the big slotted screws that held the side cover on. he said that they were used on old stoves but all the cast iron stoves i see say "made in china" on them!
