Bowmalloy 36473 Hex Head Cap Screw 3/4-16 X 2-1/4 in Grade 9

Product Description

The BOWMALLOY 36473 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 9 alloy steel, it delivers tensile strength well above standard Grade 5 or Grade 8 hardware, making it a reliable choice where bolt fatigue and shear resistance matter. The clear zinc chromate finish provides corrosion protection suitable for indoor and moderately exposed environments. The 3/4-16 thread specification indicates a fine-thread UNF profile, which provides superior thread engagement and resistance to loosening under vibration.

This cap screw is suited for heavy equipment, agricultural machinery, hydraulic systems, and other assemblies that demand high-clamp-load fasteners. The fine-thread pitch and Grade 9 rating make it a common choice for OEM and MRO replacement in equipment where standard coarse-thread hardware is not specified. Sold in packages of 25, this fastener is practical for both job-site use and shop stock.

Key Features

• Grade 9 alloy steel construction for high tensile and proof load strength
• 3/4-16 UNF fine-thread profile for superior clamp load and vibration resistance
• Fully threaded shank along the 2-1/4-inch length under head
• Clear zinc chromate finish for corrosion protection in moderate environments
• Inch-system dimensions for direct compatibility with standard SAE tooling
• Package quantity of 25 for shop stock and field service use

Compatibility

Designed as a high-strength OEM-style replacement hex head cap screw for applications specifying a 3/4-16 UNF fine-thread fastener in Grade 9 alloy steel with clear zinc chromate finish.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with high-strength fastener procedures. Always verify that the mating threaded hole or nut is rated to match the Grade 9 load requirements before installation. De-energize or shut down any equipment fully before servicing fastened assemblies. Follow equipment manufacturer torque specifications and applicable industry standards when tightening.
