Hello, At the prompt of a fellow member, I am going to post the Screw Starters that I have here. Feel free to jump in with whatever you have, or, use. At top is a Rimster 5/16 Hex Starter. Next is a more modern tool, a Klein Phillips Screw Starter, non-magnetic, I had to buy it for brass hardware. All of the rest are for slotted screws. The next 2 are a spring clip style, Channellock, and a Lok-Blok Patent. Next is an Ideal Industries, 2 prongs, that are opened/closed by a sliding barrel. The next is a Miner Tool Co., it has 2 fixed prongs, and by sliding the short barrel at the end it opens/closes a third prong to engage the screw. The next 6 have 2 fixed prongs, and by twisting the knurled collar, it opens/closes a third prong to engage the screw. The makers are Vulcan (long one with the magnet end), the two 5" ones are Aircraft Specialties, and unmarked. The 3 shorties are Ullman Devices, Proto, and New Britain. The next one is a very simple tool just a rod with 2 pieces of spring steel at each end. The bottom 3 are made by the H J J Co., in California. They are still in business, and have a great selection.These work by pressing the plunger, which closes the prongs, engage the screw, and slide the barrel toward the screw. Regards, Lou
