BRASS CARRIAGE BOLT

Product Description

Brass carriage bolts (also known as cup head square neck bolts) are specialized fasteners primarily used in woodworking and marine applications. They are distinguished by their smooth, domed head and a square neck directly underneath, which bites into the material to prevent the bolt from spinning when the nut is tightened.

Key Features & Benefits

• Self-Locking Design: The square neck locks into a pre-drilled hole (typically in wood or soft metal), allowing you to tighten the nut from one side without needing a wrench for the bolt head.

• Tamper Resistance: Because the head is smooth and rounded with no drive (like a slot or hex), it cannot be easily gripped or unscrewed from the outside, providing added security.

• Corrosion Resistance: Solid brass construction makes these bolts ideal for marine environments, outdoor furniture, and decorative restoration where rust resistance and aesthetics are vital.

• Common Applications

  • Boat Building: Used extensively in wooden hulls and deck fittings due to their resistance to saltwater corrosion.

  • Antique Restoration: Ideal for vintage trunks, decorative gates, and period-correct furniture.

  • Outdoor Construction: Perfect for pergolas, decking, and playground equipment where safety (smooth heads) and durability are required.

  • Security: Securing signs, doors, or panels where you want to prevent unauthorized removal from the exterior.
