Bowmalloy BOW36528 Hex Head Cap Screw Grade 9 Steel

Product Description

The BOWMALLOY BOW36528 is a Grade 9 steel hex head cap screw designed for high-strength fastening applications. It measures 1-14 thread size with a 7.5-inch length under the head and features partial threading along the shank. The Bowma-Guard finish provides corrosion resistance suited to demanding service environments. This fastener is installed by millwrights, maintenance mechanics, and heavy equipment technicians working on structural, agricultural, or industrial assemblies that require reliable clamping force and resistance to loosening under load.

This cap screw fits applications where Grade 9 rated fasteners are specified, including heavy equipment frames, agricultural machinery, mining equipment, and industrial structural connections. Partial threading ensures the unthreaded shank section bears shear loads without thread engagement, which is the correct configuration for many structural joint designs. Its inch-series 1-14 thread form matches standard SAE and ASME heavy hex fastener specifications.

Key Features

• Grade 9 steel construction provides high tensile and proof load ratings suitable for heavy-duty mechanical joints
• Bowma-Guard finish offers corrosion protection for outdoor and harsh-environment installations
• Partial threading allows the shank to carry shear loads independent of thread engagement
• 1-14 thread size conforms to inch-series unified thread standards
• 7.5-inch length under head accommodates thick structural members and stacked components

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for inch-series Grade 9 hex head cap screw applications specifying a 1-14 thread size and 7.5-inch grip length.

Installation Notes

Installation should be performed by qualified mechanics or millwrights familiar with high-strength fastener torque requirements. Always consult the equipment manufacturer torque specification chart for Grade 9 fasteners before tightening. Clean threads and bearing surfaces before assembly and inspect for damage. Never reuse fasteners that have been subjected to overtorque or impact loading.
