About this item
- Commercial Grade Steel Construction: built from commercial-grade carbon steel, these carriage bolts deliver consistent strength and reliability for general structural fastening; Designed for contractors and serious DIY applications where durability and dependable performance matter
- Hot-dip Galvanizing Process, Durable for Outdoor Use: unlike standard galvanized bolts, our heavy-duty hot-dip galvanizing effectively resists corrosive substances in ACQ-treated wood; Made of 307A carbon steel, they meet industry standards and are suitable for load-bearing structures, mechanical assembly, and other applications, ensuring long-term stable performance
- Extended 6-inch Thread for Deep Engagement: designed with full thread, providing deeper nut engagement and strong clamping force when fastening thick lumber or multi-layer wood assemblies
- Complete 40-set Hardware Kit: includes (60) 1/2" x 6" carriage bolts, (60) USS flat washers, and (60) hex nuts, all sized for proper fit and even load distributionโno additional hardware needed
- Ideal for Wood Exterior Construction Projects: the smooth round head with square neck helps prevent spinning during installation; Commonly applied for deck framing, fencing, pergolas, barns, gazebos, and outdoor wood structures
