What Is It? Game 137

W00t! It's time for this week's collaboration with the What Is It? Blog. Do you know what the strange screw shown above is used for?

Place your guess in the comment section. One guess per comment, please, though you can enter as many as you can think of. Write no URL or web links in the comment - doing so will invalidate your entry. The first correct guess and the funniest albeit wrong guess will win T-Shirts of their choice from the NeatoShop. You've got until the right answer is revealed at the What Is It? Blog sometime tomorrow.

IMPORTANT: Be sure to write your T-shirt selection alongside your guess. If you don't, then we'll send you a random T-shirt if you win. Visit the NeatoShop and take a look around. We've got a lot of neat Science T-shirts and Funny T-Shirts.

For more clues, check out the What Is It? Blog. Good luck!

Update 5/10/10 - the answer is: A stage screw, used to anchor stage braces to the floor, as seen in patent number 648,531. According to patent number 820,655, they could also be inserted into "walls, or upper structure to provide a fixed pint of attachment, so that cables, hooks, guy-ropes, etc, may be readily engaged with ring portions, and thus fastened to the handle, or the device may be used in connection with the various stage-settings and scenery-frames as a fastening means or coupling member."

Congratulations to Heath Hays who got it right first and to philosophile for "Mickey Mouse's Home Brain Surgery Kit."
