My socket screw says size 6-32, 3/4". What do these numbers denote and is this SAE?
Where can I get a long socket /hex head screw driver for this size?
here's a good description of what the sizes mean. that part you are looking for is toward the bottom of the page.

that is a #6 screw (.138) with 32 threads per inch. you should be able to buy the socket anywhere that sells tools. home depot or any hardware store. auto parts stores may carry them as well. yes it is SAE not metric.
