Bowmalloy 36098 Hex Head Cap Screw 7/16-14 X 7 in Grade 9

Product Description

The BOWMALLOY 36098 is a Grade 9 alloy steel hex head cap screw sized at 7/16-14 thread by 7 inches in length under the head. It features a clear zinc chromate finish for corrosion resistance and is partially threaded along the shank. This fastener is designed for high-strength bolted connections in heavy-duty mechanical, structural, and industrial assemblies. Installation is performed by mechanics, millwrights, and maintenance technicians using standard hex tooling. Grade 9 alloy steel delivers tensile strength above standard Grade 5 and Grade 8 fasteners, making it appropriate for demanding load-bearing applications.

This cap screw is suited for use in industrial equipment assembly, heavy machinery, agricultural equipment, and structural connections where high clamping force and fatigue resistance are required. The partial threading design preserves shank strength across the unthreaded grip length, which is important in applications with shear loads or close-tolerance clearance holes. The inch-series 7/16-14 thread pitch conforms to Unified National Coarse standards, which are common in North American mechanical and manufacturing environments.

Key Features

• Grade 9 alloy steel construction for high tensile and proof load strength
• Clear zinc chromate finish provides corrosion protection in standard service environments
• Partially threaded shank preserves grip-length integrity under shear loading
• 7/16-14 Unified National Coarse thread for broad tooling and nut compatibility
• 7-inch length under head accommodates thick stack-ups and long-reach fastening applications

Compatibility

Designed as a standard inch-series hex head cap screw for use with 7/16-14 threaded nuts, inserts, and tapped holes in Grade 9-rated assemblies across industrial, agricultural, and heavy mechanical applications.

Installation Notes

Installation should be performed by qualified mechanics or maintenance technicians using calibrated torque tooling appropriate for Grade 9 fasteners. De-energize or lock out equipment before replacing fasteners in live machinery per applicable safety procedures. Do not mix Grade 9 hardware with lower-grade nuts or washers, as mismatched hardware can compromise joint integrity. Fastener threads and bearing surfaces should be inspected for damage before installation.
