You can try ordering them from McMASTER-CARR (http://www.mcmaster.com/). Grade 8 are usually gold but are expensive or you can get stainless for a decent price (Not Gold but you won’t have to worry about rust so just paint them). If you find something you should get them in a day or two.
Here are two P/Ns (Stainless) that might work for you:
- 91287A136 ($17.27 for 100pcs 18-8SS)
- 93635A210 ($12.46 for 50pcs 316SS)
Then for washers just pick something you like with a hole ID of .236" or higher.
- 90965A170 ($6.62 for 100pcs 316SS)
- 93475A250 ($3.14 for 100pcs 18-8SS)
