Conquest 5/8" x 16" A307 Carriage Bolt with Galvanized Finish
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.
Built for durability in outdoor and high-moisture environments, the Conquest 5/8" A307 Carriage Bolt features a hot dip galvanized finish and coarse 11 threads per inch (TPI) for superior hold in structural wood-to-wood or wood-to-metal fastening. The smooth round head and square neck design prevent bolt rotation while offering a clean, tamper-resistant finish.
A307 Carriage Bolts for Decks, Frames & Marine Projects
Engineered to meet ASTM A307 standards, these carriage bolts are a go-to choice for contractors, builders, and professionals working with treated lumber, fencing, and outdoor assemblies. Pair with hot dip galvanized nuts and washers for corrosion-resistant fastening that lasts.
Key Features
- ASTM A307 Grade A: Low-carbon steel bolt rated for general-purpose structural use.
- Hot Dip Galvanized Coating: Long-lasting rust protection in wet or outdoor environments.
- Square Neck Lock: Resists spinning during tightening, ideal for single-sided installs.
- Domed Head: Low-profile, smooth finish suitable for exposed applications.
- Coarse Thread (11 TPI): Secure grip for heavy-duty fastening in wood and metal.
- Versatile Applications: Great for decking, timber framing, fencing, dock assembly, and structural wood builds.
Common Applications
- Deck construction in outdoor and high-moisture environments
- Wood fencing installations including treated lumber and pasture fencing
- Pergolas, timber frames, and other outdoor wooden structures
- Marine or coastal projects where corrosion resistance is critical
- Structural wood-to-wood or wood-to-metal joints in construction and landscaping
Installation Tips
- Drill a clearance hole so the square neck seats securely into the wood and prevents spinning
- Use only hot dip galvanized nuts and washers to maintain full corrosion resistance and proper thread fit
- Tighten from the nut side using a wrench or socket, no need to grip the head
- Ensure full thread engagement when selecting bolt length based on material thickness
- Recheck connections periodically in high-vibration or outdoor installations for long-term integrity
