Bowmalloy BOW36224 Hex Head Cap Screw Grade 9 Steel

Product Description

The BOWMALLOY BOW36224 is a Grade 9 steel hex head cap screw designed for high-strength fastening in demanding industrial and mechanical applications. Measuring 1-8 thread size with a 5.5-inch length under head, this fastener features partial threading and a Bowma-Guard zinc-plated clear chromate finish that provides corrosion resistance in service environments. The hex head drive configuration is compatible with standard hex wrenches and impact tools. Grade 9 classification indicates a high-strength fastener suitable for heavy-duty bolted connections where tensile strength requirements exceed standard Grade 5 or Grade 8 specs.

This cap screw is suited for heavy equipment assembly, structural fastening, and mechanical installations where high clamping load and corrosion protection are required. The partial threading allows for accurate load distribution across unthreaded shank sections, making it appropriate for applications involving shear loads or precise joint alignment. It is sold in packages of 10 and is specified in inch measurements throughout.

Installation Notes

Installation should be performed by qualified mechanics or tradespeople familiar with high-strength fastener procedures. Follow applicable industry standards such as ASME or AISC guidelines for proper torque and joint preload when tightening Grade 9 fasteners. Inspect mating threads for damage or contamination before installation. Do not substitute Grade 9 fasteners with lower-grade hardware in high-load applications without engineering review.
