Being a woodworker I was aware of of the above sources, but could not find then in stainless steel, only zinc which means they have the possibly of rusting.
John had all the screws for the project I needed except the 1 1/2" pan head, 1172922. It's nice to have extras from other projects.
Should be able to check Fastenal's site to get local dealer location. If not PM me.

**used on project, other as reference and price if needed in future.
note 1: HD price for # 8 x 1 1/2" zinc screws per 100 was $5.83.
Haven't counted the exact amount of a specific screw that will be used, but do not expect it to exceed 100.
Hope this helps,
Chris
