Description

Conquest 316 Stainless Steel Carriage Bolts are built for durability in the harshest environments. Whether you're assembling marine equipment, securing outdoor structures, or tackling any job where rust is a concern, these bolts deliver long-term performance you can trust. Featuring a smooth, domed head and square neck design, carriage bolts provide a clean finish and a secure grip that resists spinning during installation. The 316 stainless steel construction offers superior corrosion resistance, especially in coastal and chemical-exposure environments - making them a top choice for pros and DIYers alike. These coach bolts pair with compatible 316 stainless steel hex nuts and 316 stainless steel washers.

Key Features

  • 316 Stainless Steel: Premium corrosion resistance, ideal for marine, coastal, or chemically-exposed environments.
  • Smooth Domed Head: Offers a clean, low-profile finish while deterring tampering.
  • Square Neck Design: Prevents rotation when properly seated in wood or square holes.
  • Threaded Shank: Compatible with standard 1/4"-20 coarse-thread nuts and washers.
  • Available in Multiple Lengths: Select the perfect size for your application with options ranging from short to extended lengths.

Applications

  • Marine construction and dock hardware
  • Outdoor furniture and decking
  • Pergolas, gazebos, and fencing
  • Trailer and equipment assembly
  • General-purpose construction in corrosive or high-moisture areas

Installation

Carriage bolts are designed for use in pre-drilled holes. Insert the bolt through the material so the square neck fits snugly into a square or pressure-fit round hole to prevent spinning. Secure with a compatible 1/4"-20 nut and washer (sold separately). Torque using a wrench or socket from the nut side, no need to grip the head.

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
