Good Screw Sizes fo General Use

[iggy_gim]

Thank you guys so much. We are going to use 8-32, 10-32, and 1/4-20 with nylocks (Keps just don't appeal to me...). We have a sponsor that will buy them for us for free off of Grainger.

By the way, I was looking on Grainger's website for wire too, I don't get teh difference between the different types of wire. What type of wire is best for our applications (I need to get this order in by Sunday and my coach doesn't know too much about materials as organization...)

If you're building a house (no motion except in the occasional earthquake), go solid-core with THN insulation. If you're building a robot or a car (something that moves), go stranded, especially for anything above about 20 GA, and a more flexible insulation. If you want to buy local (vice online), go to the local auto parts shop, not the home improvement warehouse. All of their stuff is also for 12V, great for robots. Buying the red/black "zipcord" pairs really helps layout as well. Though honestly, for 6GA (battery to main breaker to PDB) you can probably do just as well buying a nice pair of HD jumper cables at the auto shop and cutting them up as trying to find the wire. One thing to watch when buying auto electrical though -- be sure you don't buy stuff that depends on a chassis ground -- this is specifically illegal for FRC, at least in recent years.
