Bowmalloy 36212 Hex Head Cap Screw 7/8-9 X 10 in Grade 9

Product Description

The BOWMALLOY 36212 is a Grade 9 alloy steel hex head cap screw designed for high-strength fastening applications where superior tensile strength and corrosion resistance are required. Measuring 7/8-9 thread size by 10 inches in length under the head, this partially threaded fastener features a zinc-plated clear chromate finish that provides a baseline level of corrosion protection. It is installed by millwrights, ironworkers, heavy equipment mechanics, and maintenance technicians working on structural assemblies, heavy machinery, and industrial equipment where Grade 9 hardware is specified.

This cap screw is suited for heavy-duty industrial and structural applications that demand high clamping force and reliable fastener performance. The 7/8-9 coarse thread and 10-inch length make it appropriate for thick structural members, large fabricated assemblies, and equipment frames where a standard or Grade 8 fastener does not meet the load requirement. It ships in a package quantity of two.

Key Features

• Grade 9 alloy steel construction provides higher proof load and tensile strength than Grade 8
• Zinc-plated clear chromate finish offers baseline corrosion resistance for indoor and sheltered outdoor use
• Partial threading allows full bearing load on the shank in structural joint applications
• 7/8-9 UNC coarse thread for compatibility with standard inch-series nuts and tapped holes
• 10-inch length accommodates thick structural members and stacked assemblies

Compatibility

Designed for use with standard 7/8-9 inch-series hex nuts, flat washers, and lock washers in heavy-duty structural and industrial fastening applications.

Installation Notes

Installation should be performed by qualified mechanics or tradespeople following applicable structural or equipment assembly specifications. Always confirm the required torque specification from the equipment or structure OEM documentation before tightening, as Grade 9 fasteners require specific torque values not covered here. Use calibrated torque tooling appropriate for the fastener size. Inspect threads on both the screw and mating nut for damage or contamination before assembly.
