Engineered for maximum strength, these Grade 8 Zinc Yellow Plated Carriage Bolts measure 1/4-20 x 5-1/2 and deliver reliable performance in heavy-duty wood and metal assemblies. The yellow zinc finish provides corrosion resistance and a durable, attractive appearance for indoor and outdoor projects.

  • Zinc Yellow Plated finish offers superior corrosion resistance with a distinctive gold-tone appearance.
  • Carriage bolt design features a domed head and square neck to prevent rotation during tightening.
  • Thread size 1/4-20 UNC (coarse thread) for robust fastening in wood-to-wood assemblies.
  • Length 5-1/2 inches (measured under the head) suitable for through-hole or through-bolting installations.
  • Designed to be used with standard nuts and washers where required for secure, lasting connections.
  • Ideal for outdoor decking, furniture, machinery housings, and other heavy-duty applications.

For best results, pair these bolts with the appropriate nuts and, when needed, washers to distribute load. The combination of Grade 8 strength, Zinc Yellow Plated finish, and the classic carriage bolt geometry provides reliable performance in a variety of environments.
