Mounting Screw Sizing

The 3 RGB LED 17mm Lamp Board

New in the tedious job category is working out the size of screws. Normally you can just get vernier calipers in there, but sometimes things have odd shapes and weird get-in-the-way-things and you have to be creative or guess.

Enter the 3 RGB LED 17mm lamp board.

What size head fits in here? Well 3mm and a bit... So I made some screw things so I can test for fit, and measure that which fits best for accuracy.

Screw Things

Above you can see an m1.7 metal screw, and an m2, m2.5, and m3 "screw thing". The m2.5 fits :-)
