Value Collection 440362PR Hex Head Cap Screw 1/2-13x5 L9

Product Description

The VALUE COLLECTION 440362PR is a partially threaded hex head cap screw designed for high-strength bolted connections in demanding industrial and mechanical applications. Manufactured from Grade L9 steel and finished with a zinc yellow dichromate coating, this fastener delivers corrosion resistance alongside the elevated tensile strength associated with L9 alloy specifications. The 1/2-13 UNC thread pattern and 5-inch length under head make it well suited for through-bolt and structural fastening tasks where standard Grade 5 or Grade 8 hardware is insufficient. Installation requires a 3/4-inch hex wrench or socket. This screw is sold individually with a minimum order quantity of 2.

This cap screw fits into heavy-duty mechanical assemblies, industrial equipment, and structural fabrication work where high-clamp-load fasteners are specified. The partial threading allows the unthreaded shank to bear shear loads, a characteristic valued in applications such as clevis pins, close-tolerance joints, and bracket mounting. Machinists, millwrights, industrial maintenance technicians, and fabricators commonly specify L9-grade hardware for these scenarios. It is appropriate for both new assembly and maintenance replacement work in manufacturing, agricultural equipment, and heavy machinery.

Key Features

• Grade L9 alloy steel construction for high tensile strength beyond standard Grade 8 specifications
• Zinc yellow dichromate finish provides corrosion resistance in moderate-exposure environments
• Partial threading allows the unthreaded shank to carry shear loads in close-tolerance joints
• 1/2-13 UNC thread standard ensures broad compatibility with standard inch-series nuts and tapped holes
• 3/4-inch hex drive accommodates standard sockets and open-end wrenches

Compatibility

Designed as a high-strength replacement or new-assembly fastener for applications specifying 1/2-13 UNC partially threaded hex head cap screws in Grade L9 steel.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with torque specifications for the host assembly. Always de-energize or lock out equipment before servicing fastened joints per applicable OSHA lockout/tagout procedures. Use the correct 3/4-inch hex socket or wrench to avoid rounding the head. Do not substitute this fastener in applications requiring a different grade without engineering approval, as clamp load and proof load values differ between grades.
