Hello, Today is a good day for sorting, it's raining!. I have already gone through a few hundred drill bits and taps, so today is Allen Wrench day. These, like the drill bits, and taps ( mostly from machinist box clean-outs) go through a pre-sorting, damaged, bent and broken go in the scrap bin. Then I separate the imports and the non-labeled ones from the USA labels, and the rusty ones (USA) go in the tumbler. I use these to create sets, or fill in sets. I came across these 3 stamped MAC-IT, a company in Lancaster PA, that has been around for a long time, and still in business.Looks like a great source for fasteners for machinists, and they still make/sell Hex wrench kits. Regards, Lou
