Technical Specifications

Technical Features

• 1/2-13 coarse thread pitch: Provides faster thread engagement and improved resistance to cross-threading, suitable for general structural assembly.
• 6-1/2 in. length: Accommodates thicker material stacks and deeper fastening depths where shorter fasteners are insufficient.
• Galvanized finish: Applies a zinc-based coating that offers corrosion resistance, extending service life in moist or outdoor environments.
• Hexagonal head design: Engineered for wrench-driven installation, enabling controlled torque application and secure seating.
• Grade 2 classification: Meets standard low-carbon steel specifications suitable for non-critical general fastening applications.
• Sold in a box of 25: Provides job-site quantity for multi-point fastening tasks without requiring individual unit sourcing.

Applications

• General construction and structural assembly where coarse-thread hex fasteners are specified.
• Outdoor and exposed installations where a galvanized finish is required for corrosion resistance.
• Woodworking, framing, and fixture mounting requiring a 1/2 in. diameter fastener with extended length.
• Any application requiring wrench-driven installation with standard hex tooling.
