Value Collection 440860BR Hex Cap Screw 3/4-10 X 9 in Grade L9

Product Description

The VALUE COLLECTION 440860BR is a 3/4-10 UNC hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade L9 alloy steel with a tensile strength of 180,000 psi, this fastener is built for demanding bolted joints where standard Grade 5 or Grade 8 hardware is insufficient. The 9-inch length under head with partial threading allows for full engagement in thick material sections while maintaining clamping force across the joint. The zinc yellow dichromate finish provides corrosion resistance in exposed or moderately harsh environments. Installation requires a 1-1/8-inch hex wrench or socket.

This cap screw is suited for heavy equipment maintenance, hydraulic and pneumatic system mounting, large-bore flange assemblies, and structural steel connections where high preload is required. Partial threading is appropriate for applications where the shank must pass through a clearance hole before engaging a tapped bore or nut. Machinists, millwrights, pipefitters, and maintenance technicians working on industrial machinery and process equipment are the primary installers of fasteners in this size and grade class.

Key Features

• Grade L9 alloy steel with 180,000 psi tensile strength for high-load bolted connections
• 3/4-10 UNC thread form for broad compatibility with standard tapped holes and hex nuts
• 9-inch length under head accommodates thick stack-ups and deep through-bolt applications
• Partially threaded shank maintains shear strength and suits clearance-fit installations
• Zinc yellow dichromate finish provides corrosion resistance in moderate service environments
• 1-1/8-inch hex drive accepts standard sockets and open-end wrenches

Compatibility

Designed as an OEM-style replacement or maintenance fastener for industrial and mechanical assemblies requiring a 3/4-10 UNC hex head cap screw in Grade L9 alloy steel at 9 inches in length.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with high-strength fastener torque practices. Always verify that the mating tapped hole or nut grade is compatible with Grade L9 preload requirements before installation. De-energize and lock out all equipment per applicable OSHA lockout/tagout procedures before accessing fastener locations on machinery. Do not substitute impact installation for controlled torque procedures where joint integrity is critical.
