Value Collection 440274PR Hex Cap Screw 7/16-14 X 3 in Grade L9

Product Description

The VALUE COLLECTION 440274PR is a partially threaded hex head cap screw designed for high-strength fastening applications in industrial and mechanical assemblies. Manufactured from Grade L9 steel, this fastener delivers exceptional tensile strength suitable for demanding joint applications where standard Grade 5 or Grade 8 hardware falls short. The zinc yellow dichromate finish provides corrosion resistance in moderately harsh environments. Thread size is 7/16-14 UNC with a 3-inch length under head. Installation requires a 5/8-inch hex key or wrench. This screw is installed by machinists, millwrights, maintenance technicians, and general contractors working on structural or mechanical assemblies.

The 440274PR is suited for use in heavy equipment, industrial machinery, structural steel connections, and mechanical assemblies requiring a partially threaded fastener. The UNC thread form is standard in inch-based systems across North American manufacturing and maintenance environments. Partial threading provides a shank section that supports shear loads and precise joint clamping. This screw is appropriate for both original equipment assembly and field repair applications where Grade L9 performance is specified.

Key Features

• Grade L9 steel construction for high tensile strength fastening
• Zinc yellow dichromate finish for moderate corrosion resistance
• Partially threaded shank supports shear load applications
• 7/16-14 UNC thread form compatible with standard inch-system hardware
• 5/8-inch hex drive for installation with standard wrenches or sockets
• 3-inch length under head suits medium-depth clamping applications

Compatibility

Designed as a standard inch-series hex head cap screw for use in any assembly specifying a 7/16-14 UNC partially threaded fastener with Grade L9 steel properties and zinc yellow dichromate finish.

Installation Notes

Install with a 5/8-inch open-end, box-end, or socket wrench to the torque specification called out in the applicable engineering drawing or equipment service manual. De-energize and lock out all equipment before replacing fasteners in live mechanical assemblies. Do not substitute a lower-grade fastener in joints that specify Grade L9. Inspect mating threads for damage or contamination before installation to ensure full thread engagement.
