Bowmalloy BOW36205 Hex Head Cap Screw 7/8-9 X 6 in Grade 9

Product Description

The BOWMALLOY BOW36205 is a Grade 9 steel hex head cap screw designed for high-strength bolted connections in demanding industrial and mechanical applications. Measuring 7/8-9 thread size at 6 inches under the head, this fastener is partially threaded to provide a clean shank section for shear-load joints. The Bowma-Guard finish delivers a zinc-plated clear chromate coating that provides corrosion resistance in both indoor and outdoor environments. Installers working in structural, heavy equipment, or industrial maintenance applications will find this screw meets the tensile requirements of Grade 9 specifications.

This cap screw is suited for heavy-duty bolted assemblies in industrial machinery, agricultural equipment, construction equipment, and structural steel fabrication. The 7/8-9 UNC thread profile is a standard coarse-thread size widely used in North American manufacturing. Partial threading makes it appropriate for applications where the bolt shank passes through a clearance hole before engaging a tapped hole or nut, distributing shear loads across the unthreaded section.

Key Features

• Grade 9 steel construction for high tensile strength in demanding load applications
• 7/8-9 UNC coarse thread, a standard inch-series profile for broad tool and hardware compatibility
• 6-inch length under head accommodates thick stack assemblies or deep-clearance joints
• Partial threading provides a full shank section suitable for shear-load and slip-critical connections
• Bowma-Guard zinc-plated clear chromate finish for corrosion resistance
• Sold in packages of 10 with a minimum order quantity of 1 package

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 7/8-9 UNC tapped holes and standard hex nuts across industrial, agricultural, and construction equipment applications.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a properly sized hex wrench or socket. Always confirm hole thread form and pitch match 7/8-9 UNC before installation to avoid cross-threading. Apply appropriate thread lubricant or anti-seize compound as required by the joint specification. Torque to the value specified by the equipment manufacturer or applicable engineering standard for Grade 9 fasteners.
