Wholesale Tool is offering Heimann transfer screw sets at great prices — the one pictured above is $13.24. A transfer screw works a lot like a transfer punch, but it transfers the center of a threaded hole to another workpiece. You screw it into the hole, put the other piece over it, whack it with a hammer, and presto, all the hole locations are marked. I’ve provided a link for the #8-32 set, but other thread pitches are similarly priced. Each set includes six transfer screws and a container that doubles as a wrench for screwing them into the hole.
