42mm is a standard socket. If you mean "what SAE socket fits," none of them do. BTW, what are you trying to get off that's got a nut that big on it?
SAE J475 is a specification for thread sizes on tubing. 38 may be a typographic error for a 3/8" thread.
Just a basic socket set SAE or metric depending on car.
My 93gmc z71 was 13/8 sae
There are many sizes.
No. They both have totally different pin sizes and amount of pins. Socket AM2 has a lot more pins, socket a has 462 pins.
Spark plugs use SAE and not Metric. The one that fits it is the one that fits it.
Usually the size of socket comes in a socket set. Most common size is 5/8.
Unsure exactly what it is that is being asked about. The part number of the switch, or the size of the socket used to install it. Whatever. . . it will be in millimeters, there are no SAE parts on the vehicle
Some where around 15/32 or 31/64.... its a 12mm... that's it... either you're working on something metric, or you're not. Use the right socket for the job. You'll be happier if you do. Incidentally, the nearest standard/SAE size is 7/16 which is smaller.
Sae Sae Norris is 5' 5".
T55 sockets refer to SAE sizes. (Standard Automotive Engineering). M14 is a metric size.
