Description

Conquest 1/2" x 1-1/2" 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 1/2" 316 Stainless Steel Carriage Bolts are engineered for maximum durability in the harshest environments. Crafted from premium 316 stainless steel, these bolts resist rust and corrosion in marine, coastal, and chemically exposed conditions—making them an excellent choice for professionals and serious DIYers alike.

1/2" 316 Stainless Steel Carriage Bolt – Corrosion‑Resistant Fastening

Featuring a smooth domed head and square neck design, these carriage bolts deliver a clean, finished look while preventing rotation during installation. Pair them with compatible 316 stainless steel hex nuts and washers for long‑lasting, secure fastening.

Key Features

  • 316 Stainless Steel: Premium corrosion resistance for marine, coastal, and corrosive environments.
  • Thread Type: Coarse
  • Threads Per Inch: 13 TPI for strong engagement in wood and metal substrates.
  • Head Type: Smooth Domed Head with Square Neck design prevents bolt rotation once seated.
  • Wide Size Range: Available in multiple lengths to accommodate various applications.
  • Finished Appearance: Ideal for exposed applications like decks and outdoor furniture.

Applications

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

Installation

  • Drill a clearance hole and insert the bolt so the square neck seats tightly in wood or a square hole.
  • Prevents bolt rotation during tightening without needing to grip the head.
  • Secure with compatible 316 stainless steel nut and washer (sold separately).
  • Torque from the nut side with a wrench or socket for best results.

Had the fasteners

Had a little trouble getting through the first step. The size i was looking for didn't show up, but I clicked on a simular bolt which takes you the real menu. Then I was able to put in all the specs and found exactly what I was looking for. Don't give up if your first search doesn't display the part you want.

The shipment arrived and is in great shape. However, it was delayed, which is fine, but after three notices of ‘your delivery will be there tomorrow’ I had no confidence and was annoyed with the updates.
