The VALUE COLLECTION HCI50620300G-025BX is a 5/8-11 partially threaded hex head cap screw measuring 3 inches under the head. Manufactured from Grade 5 steel with a hot-dipped galvanized finish, this fastener is suited for structural and mechanical connections where moderate tensile strength and corrosion resistance are both required. The UNC thread form ensures broad compatibility with standard inch-system tapped holes and nuts. Licensed tradespeople and maintenance professionals reach for Grade 5 galvanized fasteners in outdoor, exposed, or high-moisture environments where bare steel would corrode prematurely.
This screw is appropriate for general structural assembly, mechanical equipment mounting, and utility installations in residential and commercial settings. Partial threading allows the unthreaded shank to bear shear loads, making it a practical choice for bolted connections through clearance holes in steel, wood, or composite materials. Plumbers, electricians, HVAC technicians, and general contractors commonly stock fasteners of this specification for equipment mounting, strut assembly, and field fabrication tasks.
Designed for use with standard 5/8-11 UNC hex nuts, washers, and tapped components conforming to inch-system fastener specifications.
Installation is typically performed by any qualified tradesperson using a standard 15/16-inch wrench or socket. Apply appropriate torque for Grade 5 fasteners per applicable project specifications or relevant codes such as AISC or OSHA standards for structural bolting. Use flat washers as needed to distribute load and protect mating surfaces. Inspect threads and galvanized coating for damage before installation and do not use fasteners with cracked or missing coating in corrosive service.
