Value Collection 440930BR Hex Head Cap Screw 1-1/4-7 X 5 in

Product Description

The VALUE COLLECTION 440930BR is a partially threaded hex head cap screw designed for heavy-duty bolted joint applications. Manufactured from Grade L9 steel, this fastener carries a minimum tensile strength of 180,000 psi, making it suitable for high-stress mechanical assemblies. The 1-1/4-7 UNC thread and 5-inch length under head accommodate thick structural members and flanged connections. A zinc yellow dichromate finish provides corrosion resistance in industrial and outdoor environments. Licensed mechanics, millwrights, and maintenance technicians regularly specify L9-rated hardware where standard Grade 5 or Grade 8 fasteners do not meet load requirements.

This cap screw is used in industrial machinery, heavy equipment, structural steel assemblies, and fabrication applications where high clamping force and fatigue resistance are critical. The partially threaded shank allows the unthreaded portion to carry shear loads without thread engagement at the shear plane. The 1-7/8-inch hex key size accommodates standard industrial wrenching tools. This fastener is sold in single-unit quantities, suitable for maintenance, repair, and operations procurement as well as project-specific sourcing.

Key Features

• Grade L9 steel construction with 180,000 psi minimum tensile strength for high-load applications
• Partially threaded shank isolates shear loads from the threaded zone
• 1-1/4-7 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• Zinc yellow dichromate finish for corrosion resistance in industrial environments
• 1-7/8-inch hex drive size compatible with standard heavy-hex wrenching tools

Compatibility

Designed as an OEM-style replacement or maintenance fastener for heavy-duty industrial bolted assemblies requiring 1-1/4-7 UNC partially threaded hex head cap screws in Grade L9 steel.

Installation Notes

Installation should be performed by qualified mechanics or millwrights familiar with high-strength fastener torque requirements. Always verify mating nut or tapped hole grade is rated to match or exceed the fastener tensile strength before assembly. Follow applicable ASME or equipment OEM torque specifications for 1-1/4-7 UNC fasteners at the required clamp load. Inspect threads and seating surfaces for damage before installation, and do not reuse fasteners that show signs of yielding or thread deformation.
