Conquest 1/4" 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.

Conquest 1/4" 316 Stainless Steel Carriage Bolts are engineered for demanding environments where corrosion resistance and long‑term reliability matter most. Constructed from premium 316 stainless steel, these bolts perform exceptionally well in marine, coastal, and chemically exposed settings, making them ideal for construction professionals and DIYers alike.

1/4" Conquest 316 Stainless Steel Carriage Bolt – Corrosion‑Resistant Fastening

The smooth domed head and square neck design deliver a clean finished look while preventing the bolt from spinning during installation. These carriage bolts pair perfectly with compatible 316 stainless steel hex nuts and washers for secure, long‑lasting fastening.

Key Features

  • 316 Stainless Steel Construction: Premium corrosion resistance for outdoor, marine, and high‑moisture environments.
  • Thread Type: Coarse
  • Threads Per Inch: 20 TPI for secure engagement.
  • Round, Smooth Domed Head: Offers a polished, low‑profile appearance.
  • Square Neck Design: Locks the bolt in wood or metal to prevent spinning during tightening.
  • Wide Length Options: Available in multiple lengths to suit different material thicknesses and project needs.

Applications

  • Marine construction and dock hardware
  • Outdoor furniture, decking, and boardwalks
  • Pergolas, gazebos, fencing, and railings
  • Trailer hardware and equipment assembly
  • Any construction or repair in corrosive or high‑moisture areas

Installation

  • Drill a clearance hole through the material so the square neck seats firmly.
  • Insert the bolt so the square neck bites into wood or a square hole to prevent rotation.
  • Secure with a compatible 316 stainless steel nut and washer (sold separately).
  • Tighten from the nut side using a wrench or socket—no need to grip the head.

Carriage Bolts

A rough sawmill cut 6X6 my very well split. My remedy for this problem is to fill the crack with silicone and bolt the crack with a half inch 316 stainless steel 7 inches long with a 316 flat washer, lock washer, and hex nut.
I’ve been a returning customer with these folks for years and will continue doing business with them as I’ve never found service any better and with competitive pricing on all their wares that I’ve used. They’re the best!
