Conquest 5/8" x 6" 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

Great hard-to-find products that are high quality. Unbelievable customer service.
I had a box damaged during shipping and they were quick to respond and expedited me replacements for the job.
It wasn't their fault but they went above and beyond to make it right.
I needed 170 - 6-inch carriage bolts to stitch together some LVL material.
Your pricing and quick shipping helped me save time and money.
Thanks
