Zinc 1/2-13 x 6 Coarse Hex Cap - Grade 5

Overview

Zinc 1/2-13 x 6 Coarse Hex Cap - Grade 5 (349) is designed for hardware fastening applications requiring high-strength threaded connections in general construction, structural assembly, and mechanical installations.

Technical Features

• Grade 5 high-strength classification — meets medium-strength fastener standards, providing reliable tensile and proof load performance for structural and mechanical connections.
• Zinc finish — provides a corrosion-inhibiting surface coating, extending service life in general-duty environments and reducing oxidation on exposed fastener surfaces.
• 1/2-13 coarse thread pitch — coarse threading allows faster engagement and installation, and offers increased resistance to cross-threading compared to fine-thread variants.
• 6-inch length — accommodates deep through-hole and thick-material fastening applications where standard shorter bolts are insufficient.
• Hex drive type — compatible with standard hex wrenches and sockets, enabling high-torque installation with commonly available hand and power tools.

Applications

• General construction and structural bolted connections requiring Grade 5 strength ratings.
• Mechanical assemblies where a coarse 1/2-13 thread pattern and extended 6-inch grip length are specified.
• Equipment fabrication and framing applications where zinc-coated fasteners provide adequate corrosion resistance for indoor or sheltered outdoor use.
• Any installation requiring a hex-driven cap screw compatible with standard wrenching tools.
