Overview
The AMM Hex Allen Wrench set includes 19 pieces with a stated length of 4.3 inches, sold under the AMM tools brand. It has a 4.6 star rating from 968 reviews and about 600 purchases a month.
A 19 piece count on a hex wrench set typically spans both metric and SAE sizes plus a couple of specialty or ball end keys, though this listing does not break down the individual sizes included. The 4.3 inch length figure most likely describes the longest wrench in the set rather than every piece, since hex key sets are normally graduated in size.
