The next time you are at the Dollar store, pick up one of the large number calculators. If you take it apart you will have about a dozen small wood screws that are perfect for windshield installation.

A hobby shop which caters to model railroad will have a supply of small screws, washers, nuts and bolts. Probably more expensive, of course.

You can get bags of that stuff from RTL Fasteners

Seems like a waste of a good calculator!

I forgot to mention that the calculator had a dead battery and the battery cost more than $1. Just a pleasant surprise to stumble across the screws I needed from something I was going to through away. motorhd

ACE Hardware has all the RC hobby sizes of locknutes, bolts, nuts, blindnuts, nylon, etc, etc and cheap prices.
