    When I worked at a Chevy dealer in the 60's the step vans ( Boyertown bodies IIRC) were screwed together with clutch heads. You go to the hardware store today almost all the screws you see are Philips heads. Why, because almost everyone has a battery powered drill or screwdriver. Clutch heads were an early attempt to keep the screw centered up on the speed or power driver of the day.

    I deal with the clutch heads on my AD truck. I dont like them and the will be replaced with philips head screws. The fasteners i dislike even more than clutch head are tri wings. They are great for securing something, but they are a pain to remove. I have never had to drill a clutch head, but i lost count of the number of tri wings. There is always something worse.

    I bet I`ve boughten at least 20 of these kits over the years. I`ve given them out at X-mas. The y shaped attatchment in the upper corner is for eye screws.------- Now that you know what a clutch head is. You will buy every tool for these you see for the next couple years. I have a drawer dedicated just for clutch headed screwdrivers, bits and socket adapters. Also know to be called apple cores.

    Try looking for the tool to remove these when not knowing what the they were called. It was 25 years ago. Didn`t have a screw to show them what it was. I educated the parts store owner that day, as well as a couple other people as well.

    John Deere had the best idea for clutch head use. These made for short work on the assembly line using powered drivers, and when Old MacDonald out on the farm had to work on his new Model A tractor (yes, John Deere also had a model A. And a Model B) he could use the wrenches he had in the tool shed.

    The first link posted, confused Clutch drive screws with "one way" tamper proof screws.

    Countersunk clutch drive screws are used to hold the camshaft thrust plate on early Ford small blocks.

    It's just a case of buying the correct tool to do the job.

    You guys down there probably don't like our "Robertson" head screws either.
