The VALUE COLLECTION HCI50870250G is a fully threaded hex head cap screw sized 7/8-9 UNC with a 2.5-inch length under head. Manufactured from Grade 5 steel and finished with a hot-dipped galvanized coating, this fastener delivers solid tensile strength and corrosion resistance suited for structural and mechanical assembly work. The UNC thread standard and full threading along the shank make it compatible with standard hex nuts and tapped holes without the need for partial-thread clearance. Electricians, plumbers, HVAC technicians, and general mechanical contractors commonly use this class of fastener for equipment mounting, bracket installation, and structural panel assembly.
This screw is appropriate for indoor and outdoor applications where corrosion exposure is a concern. The hot-dipped galvanized finish provides a zinc coating that resists rust in moderately harsh environments, including exterior mechanical equipment pads, rooftop HVAC mounting, utility brackets, and general trade construction. It is sold individually and is suited for both single-unit replacement and small-quantity installation jobs where precise fastener spec matching is required.
Designed as a standard 7/8-9 UNC hex head cap screw for use with matching UNC hex nuts, flat washers, and lock washers in structural or mechanical fastening applications.
Install using a standard hex wrench or socket set sized for a 7/8-9 fastener. Power down or de-energize any equipment before fastening components to live mechanical or electrical assemblies. Apply anti-seize compound if the fastener will be exposed to prolonged moisture or dissimilar metals to prevent galling. Follow applicable code requirements for fastener grade and torque specifications as defined by the equipment manufacturer or structural engineer of record.
