Free returns on all eligible orders
You have 30 days to request a return. All sale items are final sale.
Corrosion-resistant carriage bolt crafted from 18-8 stainless steel for durability in outdoor and marine environments.
Designed for joint applications where a nut is used on the opposite side, providing a smooth, domed head for a tidy finished appearance.
Parts Desk Insight: Best suited for wood-to-wood or wood-to-metal assemblies where a clean head is visible. Common issues include loosening under vibration if the nut is not securely tightened — consider locking features or proper torque during installation.
Compatible Applications:
- Wood-to-wood and wood-to-metal joints in outdoor or marine environments
- Decks, fences, frames, and other structural assemblies
- Any project that uses a nut on the opposite side for a secure connection
