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

When pairing a nut with a hex bolt, the material and finish must match. If these do not match, the nut will not fit the bolt.

Engineered for strength and long-lasting corrosion protection, the 3/8" Conquest 316 Stainless Steel Carriage Bolt is the go-to solution for professionals and demanding applications. Made from marine-grade 316 stainless steel, this bolt excels in saltwater, coastal, and chemically exposed environments.

3/8" 316 Stainless Steel Carriage Bolts with Marine-Grade Durability

Its domed, smooth head and square neck prevent rotation during tightening, offering a clean, tamper-resistant finish. Perfect for structural or aesthetic applications alike, from decks to docks and fencing to framing.

Key Features

  • Diameter: 3/8"
  • Thread Type: Coarse
  • Threads Per Inch (TPI): 16
  • Material: 316 Stainless Steel for top-tier corrosion resistance
  • Head Type: Round domed head with square neck for anti-spin installation
  • Finish: Uncoated stainless for a polished, clean appearance

Couldn’t be Happier with Fasteners plus.

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
