so is this mean that 3/8 square drive is more important to 1/4 (or same important) for large a/c? all size is AF right?
for screwdriver, do we need a set (normal screwdriver) or one ratchet screwdriver with variety of bits is enough?
oh ya, for one square drive of ratchet, there is a lot of type available. which one is the best to use? or all the same? because different type come with different price. i mean for the type of ratchet(some of them metal handle, rubber handle, swivel head, long handle) not the size of square drive.
for a and c 3/8 drive is the one to use
u rarely use 1/4 drive, maybe in tight spaces or cabin interior works
both the ratchet and normal one is ok, but if u have extra money get both.
usually the normal screwdriver tips is a lot stronger than those changeable bits
and even the screwdriver got sizes, size 1, 2 and 3...
most common is size 2, 1 is smaller than 2 and three is bigger than 2
note that airbus uses different type of screw, so different screwdriver and bits
your ratchet just get what u can afford, but get a good one, you'll use it alot
the longer one is better to release torque but its hard to use for tight spaces
just get a normal one will do, and i would suggest u to buy a 3/8 drive t-handle to break the torque before u use ur ratchet
its all depends on the budget, if u have extra money, get a (1/4 and 5/16) and (3/8-7/16) ring ratchet, it is optional and bit expensive but sometimes it comes in very handy
