You may only make use of them rarely, but when you need to reach that extra 3 or 4 inches these can't be beat. We have had a set of 10 made up for Garrett Wade - from 3/8'' all the way down to a tiny 1/16''. All are 12'' long. For what you get, these are really inexpensive and we think they belong in every well equipped shop or toolbag. Keep them tightly bundled together as a bunch and they will take up very little room and be completely safe from damage. We are very pleased to find them. Sizes: 1/16'', 1/8'', 5/32'', 3/16'', 7/32'', 1/4'', 9/32'', 5/16'', 11/32'', 3/8''
