1/2-13 x 6 Carriage Bolts - Galvanized Box/25

Overview

The Midwest Fastener Carriage Bolt, Box of 25 (5527), is designed for hardware fastening applications requiring a secure, corrosion-resistant threaded connection in wood, metal, and structural assemblies.

Technical Features

• 1/2-13 National Coarse (NC) Thread: Coarse threading allows for faster installation and greater resistance to cross-threading in rough or field-cut holes.
• 6-Inch Overall Length: Provides sufficient grip length for fastening through thicker stock material, structural lumber, or stacked assemblies.
• Round Head Profile: The domed, low-profile head seats flush against surfaces without requiring a countersink, distributing load evenly and presenting a clean finished appearance.
• Galvanized Finish: Zinc galvanizing provides a protective barrier against rust and oxidation, making these bolts suitable for outdoor, high-humidity, or moisture-exposed installations.
• Grade 2 Classification: Meets Grade 2 standards for general-purpose structural and construction fastening applications.
• Box of 25: Sold in a contractor-quantity box, reducing per-unit cost and ensuring sufficient supply for larger or repeat fastening tasks.

Applications

• Structural wood-to-wood connections in decking, framing, and fence construction where corrosion resistance is required.
• Wood-to-metal assemblies in outdoor furniture, pergolas, and agricultural structures.
• General construction and maintenance tasks requiring a 1/2-inch coarse-thread fastener with a tamper-resistant, non-rotating head.
• Dock, pier, and marine-adjacent construction where galvanized protection against moisture is essential.
