Conquest 3/8" x 2-1/2" Carriage Bolt - 316 Stainless Steel

Made from marine-grade 316 stainless steel, this bolt excels in saltwater, coastal, and chemically exposed environments.

Good price
As The title says “I couldn’t be happier”. It was easy to make the order. The items I ordered are exactly what I wanted and I didn’t have to wait two weeks or more for the shipment to arrive. I couldn’t believe how fast the items were shipped. Will definitely get any other orders for fasteners from them. I’m retired now so don’t get many projects, but sure wish I had known them back when I was in business.
Thanks you all
