Bowmalloy BOW36226 Hex Head Cap Screw Grade 9 1-8x6.5in

Product Description

The BOWMALLOY BOW36226 is a Grade 9 steel hex head cap screw designed for high-strength fastening applications in industrial and mechanical assemblies. Measuring 1-8 thread size by 6.5 inches in length under head, this fastener features partial threading and is finished with Bowma-Guard zinc-plated clear chromate coating for corrosion resistance. Grade 9 designation indicates superior tensile strength compared to standard Grade 5 or Grade 8 fasteners, making it appropriate for heavy-duty structural and equipment mounting applications. Installation is performed using standard hex drive tools.

This cap screw is suited for heavy equipment, agricultural machinery, industrial fabrication, and structural assemblies where high-torque, high-load fastening is required. The partial threading design allows for a smooth shank grip zone, which is preferred in applications where the fastener passes through a clearance hole before threading into a tapped bore. Sold in a package quantity of 2.
