What are the 3 ratchet sizes?

Available with different drive sizes — 1/4 inch, 1/2 inch and 3/8 inch — to operate different size sockets. Most operate with a geared drive; those with a higher tooth count let you operate the tool with a smaller swinging motion, which is useful when there's little room to move the handle.

What does AF mean in spanner size?

On UNF, UNC and Metric the measurement of the spanner is said to be A/F or across flats. This means that the actual size of the bolt head is the measurement of the spanner. So that a 1/2in A/F spanner will fit a bolt head of UNF, UNC which will measure 1/2in.

What is difference between metric and standard?
