Bowmalloy BOW36519 Hex Head Cap Screw Grade 9 Steel

Product Description

The BOWMALLOY BOW36519 is a Grade 9 steel hex head cap screw designed for high-strength bolted connections in demanding industrial and mechanical applications. It measures 1-14 thread size with a 3.5-inch length under the head and features partial threading along the shank. The Bowma-Guard zinc-plated clear chromate finish provides corrosion resistance in moderate-exposure environments. This fastener is installed by millwrights, maintenance mechanics, and field technicians working on heavy equipment, structural assemblies, and machinery requiring SAE Grade 9 tensile performance.

This cap screw is suited for high-load bolted joint applications where Grade 9 minimum proof strength is specified. Typical use cases include heavy equipment frames, agricultural machinery, construction equipment, and industrial fabrication assemblies. The partial threading allows the unthreaded shank to bear shear loads at the joint interface, making it appropriate for applications where shear strength matters alongside clamping force. It follows inch-series fastener standards and is sold in packages of 10 units.

Key Features

• Grade 9 steel construction meets high-strength SAE fastener requirements for heavy-duty bolted joints
• 1-14 inch thread size with 3.5-inch length under head for deep-grip applications
• Partial threading preserves an unthreaded shank section for shear-load-bearing capability
• Bowma-Guard zinc-plated clear chromate finish provides corrosion resistance in moderate environments
• Inch-series measurement system for compatibility with standard SAE tooling and hardware
• Packaged in quantities of 10 for job-site convenience

Compatibility

Designed as an inch-series Grade 9 hex head cap screw for use in high-strength bolted assemblies where 1-14 thread size and 3.5-inch grip length are specified.

Installation Notes

Installation should be performed by qualified mechanics or millwrights familiar with high-strength fastener torque procedures. Always consult the equipment manufacturer torque specification chart for Grade 9 fasteners at this thread size before tightening. Inspect the mating threaded hole or nut for thread condition and clean debris before assembly. Do not reuse fasteners that show signs of thread deformation, corrosion damage, or prior overtorque.
