The VALUE COLLECTION 403156PR is a hex head cap screw designed for general-purpose fastening in mechanical assemblies, structural connections, and equipment maintenance. Sized at 7/16-14 (7/16 inch diameter, 14 threads per inch, UNC thread standard) with a 2-3/4 inch length under head, this fastener features partial threading along the shank. It is manufactured from Grade 2 steel with a zinc-plated finish that provides a baseline level of corrosion resistance for indoor and light-duty applications. Installers across HVAC, plumbing, electrical, and general mechanical trades will find this screw compatible with standard 5/8 inch hex drives and common power tools.
This fastener is suited for use in residential and light commercial applications where Grade 2 steel meets load requirements. It is commonly used when attaching brackets, panels, equipment frames, and mechanical supports. The partial thread design allows for improved clamping force in bolted joint assemblies where the unthreaded shank passes through one or more clearance-drilled components before engaging a nut or threaded hole. It is appropriate for use with standard UNC hardware and hex nuts.
Designed as a general-purpose inch-series hex head cap screw compatible with standard 7/16-14 UNC nuts, washers, and threaded components across a wide range of mechanical and equipment fastening applications.
Install using a 5/8 inch hex socket or open-end wrench; a torque wrench is recommended for critical joint applications where clamping force must be controlled. Ensure mating threads and fastener threads are free of debris before assembly. Do not use in applications requiring Grade 5 or Grade 8 fastener ratings unless the joint design specifically permits lower-grade substitution. Zinc plating provides only light corrosion protection — evaluate suitability before use in outdoor, high-humidity, or chemical-exposure environments.
