Stainless Steel Carriage Bolts are specialized fasteners designed with a smooth, rounded head and a square neck beneath the head. This square section locks into the material during installation, preventing the bolt from turning when the nut is tightened. Unlike hex bolts or hex head bolts, carriage bolts provide a clean, tamper-resistant appearance on the exposed surface, making them ideal for applications where both security and aesthetics are important.
Manufactured from high-quality stainless steel, these fasteners offer excellent corrosion resistance and long-term durability. Stainless Steel Carriage Bolts are available in full thread bolt and half-tooth bolt configurations to suit different load and installation requirements. They are widely used in wood-to-wood and wood-to-metal connections, including construction projects, outdoor structures, furniture, fencing, and general industrial assemblies.
The square neck beneath the head prevents the bolt from spinning during installation, eliminating the need for a second wrench—a distinct advantage over traditional hex bolts.
The smooth, low-profile head is nearly impossible to grip with tools, providing a tamper-proof solution for fencing, gates, and public structures. It also minimizes the risk of snagging in high-traffic areas like decking or playgrounds.
Available in 304 and 316 stainless steel grades, these bolts resist rust and oxidation, making them ideal for outdoor furniture, coastal docks, and chemical exposure areas.
We supply both Full Thread bolt options for general-purpose fastening and Half-Tooth Bolt designs to accommodate thicker materials where a smooth shank is needed for better alignment and load distribution.
The dome-shaped head provides a much cleaner, more decorative finish compared to the industrial look of hex head bolts, enhancing the visual appeal of wood-to-metal assemblies.
Manufactured to international standards such as DIN 603 and ANSI/ASME B18.5, ensuring precise dimensions and reliable load-bearing performance for every project.
