What size wrench do you use for the big yoke bolt on an altman 510?
bolt on the instrument or on the c-clamp?
bolt that attaches the instrument to the clamp. Altman 510 being standard cclamp.
c-clamps have model numbers?
AFAIK its a 1/2"
bolt, not the size of the head.
speed wrench avkid. 99% of all 1/2" bolts measure 3/4" across flats. You can find some 1/2" bolt types especially in the nut for it that has a 7/8" across flats, but it's normally 3/4".
7/8" is the size you sometimes use on a cheeseborough, though it is more common to be 15/16" as the next size up as also used on 5/8" bolts such as for truss.
blind guessing, i use a gator grip so i have no idea!
Grip works on almost everything so i would use that or take every wrench head you got and figure it all out.
grip is one of best tools known to man
