1/2-13 x 5-1/2 Galv Coarse Hex Bolt, Gade2 Box/25

Overview

The Midwest Fastener Corp. 1/2-13 x 5-1/2 Galvanized Coarse Hex Bolt, Grade 2 (05407) is designed for general-purpose fastening applications requiring a standard hex cap screw with corrosion-resistant galvanized coating.

Technical Features

• Hexagonal head design: Engineered to be driven by a standard wrench, allowing controlled torque application and secure tightening in accessible and tight-clearance installations.
• 1/2-13 coarse thread (UNC): The unified coarse thread pitch provides faster engagement and greater resistance to cross-threading compared to fine-thread variants, streamlining assembly in field conditions.
• 5-1/2 in. length: Accommodates fastening through thicker material stacks or structural members where shorter bolts would be insufficient.
• Galvanized finish: Zinc galvanization provides a protective barrier against oxidation and moisture, extending service life in outdoor or humidity-exposed environments.
• Grade 2 classification: Meets SAE Grade 2 standards, indicating a low-carbon steel construction suitable for general-purpose, non-critical structural applications.
• Sold in a box of 25: Bulk packaging reduces per-unit cost and ensures an adequate supply for multi-fastener projects.

Applications

• General construction and structural assembly where wrench-driven hex fasteners are specified.
• Outdoor installations, fencing, decking, and framing where galvanized corrosion resistance is required.
• Light-duty mechanical and fabrication applications compatible with Grade 2 strength ratings.
• Projects requiring through-bolting of thicker lumber or layered material assemblies.
