Bowmalloy BOW36529 Hex Head Cap Screw 1-14x8 Grade 9

Product Description

The BOWMALLOY BOW36529 is a partially threaded hex head cap screw designed for high-strength fastening applications in industrial and structural assemblies. Built to Grade 9 specifications, this fastener delivers superior tensile strength over standard Grade 5 and Grade 8 hardware. It measures 1-14 thread size with an 8-inch length under the head and features a Bowma-Guard zinc-plated clear chromate finish that provides corrosion resistance in demanding environments. The inch-system threading and partial thread configuration make it well suited for clamping applications where a grip length is required between fastened components. Mechanics, millwrights, and maintenance technicians working with heavy equipment and structural steel are the primary installers.

This cap screw is used in heavy-duty industrial, agricultural, and construction equipment assemblies where Grade 9 strength is specified. The partial thread design is common in through-bolt and flange applications where precise clamping force distribution is needed along the shank. The Bowma-Guard coating helps resist oxidation in outdoor or high-humidity service environments, making it appropriate for both shop fabrication and field repair work.

Key Features

• Grade 9 steel construction for high tensile strength exceeding standard Grade 8 requirements
• Partially threaded shank provides a clean grip section for accurate clamping and alignment
• Bowma-Guard zinc-plated clear chromate finish resists corrosion in harsh service conditions
• 1-14 thread size with 8-inch length under head suits heavy structural and equipment fastening
• Inch measurement system for compatibility with standard SAE tooling and hardware

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for heavy equipment, structural assemblies, and industrial machinery applications specifying a 1-14 x 8-inch Grade 9 partially threaded hex head cap screw.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with high-strength fastener torque requirements. Always consult the equipment manufacturer torque specification chart for Grade 9 fasteners before tightening. Clean and inspect mating threads prior to installation, and replace any damaged nuts or tapped holes to ensure proper engagement. Use calibrated torque tooling appropriate for the fastener diameter and grade.
