Bowmalloy 36395 Hex Head Cap Screw 7/16-20 X 6 in Grade 9

Product Description

The BOWMALLOY 36395 is a hex head cap screw designed for high-strength fastening applications requiring reliable clamping force and corrosion resistance. It features a 7/16-20 thread size with a 6-inch length under the head and is partially threaded for proper load-bearing engagement. Constructed from Grade 9 alloy steel, this fastener delivers higher tensile strength than standard Grade 5 or Grade 8 hardware. A zinc-plated clear chromate finish provides baseline corrosion protection suitable for general industrial and mechanical assembly environments. Licensed tradespeople and industrial maintenance technicians typically specify this fastener for structural and mechanical connections.

This cap screw is suited for mechanical assemblies, equipment fabrication, and structural fastening where a fine-thread 7/16-20 pattern is required. The fine thread pitch provides greater resistance to loosening under vibration compared to coarse-thread equivalents, making it a practical choice for drivetrain components, hydraulic assemblies, and similar dynamic-load applications. Partial threading ensures proper shank engagement through clearance holes in standard bolted joint configurations.

Key Features

• Grade 9 alloy steel construction for elevated tensile strength above standard Grade 8 fasteners
• 7/16-20 fine thread pattern resists loosening in high-vibration applications
• 6-inch length under head accommodates thick material stacks or deep clearance holes
• Partial threading provides full shank engagement through clearance holes
• Zinc-plated clear chromate finish offers baseline corrosion resistance for indoor and light-duty outdoor use

Compatibility

Designed for use in standard inch-series bolted joint assemblies requiring a 7/16-20 fine thread hex head cap screw with a 6-inch grip length.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians following applicable torque specifications for Grade 9 fasteners as referenced in engineering standards. Ensure mating threaded holes or nuts are rated to match the fastener grade to avoid joint failure. Inspect the zinc-plated finish for damage before installation, as compromised coating reduces corrosion protection. Follow proper torque sequence procedures when used in multi-bolt flange or structural patterns.
