The VALUE COLLECTION HCI20750250G-020BX is a fully threaded hex head bolt designed for general structural and mechanical fastening applications. Manufactured from Grade 2 steel with a hot-dipped galvanized finish, this bolt meets ASTM A307 standards for low-carbon steel fasteners. The 3/4-10 UNC thread and 2-1/2-inch length under head make it well suited for through-bolting connections where corrosion resistance and consistent clamping load are required. Plumbers, pipefitters, HVAC technicians, and general contractors reach for this bolt when securing flanges, pipe hangers, equipment bases, and structural members in both indoor and outdoor environments.
This bolt is appropriate for residential and light commercial construction, mechanical room installations, and utility infrastructure work. The hot-dipped galvanized coating provides a durable zinc layer that resists rust in wet or exposed conditions, making it a common choice for outdoor structural connections, treated-lumber framing, and corrosion-prone mechanical environments. Sold individually, it fits jobsite and service-truck inventory restocking where single-piece quantities are practical.
Designed as an OEM-style and general-use replacement hex head bolt for 3/4-10 UNC threaded applications requiring a 2-1/2-inch length under head in steel construction.
Installation is performed by licensed tradespeople or qualified mechanics using standard 1-1/8-inch hex tooling appropriate for 3/4-inch fasteners. Apply thread lubricant or anti-seize compound as required by the applicable specification before final torque. Always verify that mating nuts, washers, and base materials are rated to the same or greater load class before fastening. Follow applicable building codes and structural specifications for torque requirements on the specific joint being assembled.
