Value Collection 403304BR Hex Head Cap Screw 7/8-9

Product Description

The VALUE COLLECTION 403304BR is a fully threaded hex head cap screw engineered for general-purpose fastening in trade and industrial applications. Sized at 7/8-9 thread with a 1-3/4 inch length under head, this fastener uses Unified National Coarse (UNC) thread standards for broad compatibility with standard tapped holes and nuts. Constructed from Grade 2 steel with a zinc-plated finish, it provides corrosion resistance suitable for indoor and light-duty outdoor use. A 1-5/16 inch hex key size allows installation with standard open-end, box-end, or socket wrenches. Installers working in mechanical, structural, or equipment-assembly contexts will find this a reliable stock fastener for routine assembly tasks.

This hex head cap screw is used across a wide range of trade applications including HVAC equipment mounting, plumbing fixture support structures, electrical enclosure assembly, and general mechanical equipment installation. Its fully threaded body makes it well suited for through-bolting applications where thread engagement along the full length of the fastener is required. The zinc plating provides moderate corrosion protection appropriate for interior installations and sheltered exterior environments.

Installation Notes

Installation requires a standard 1-5/16 inch open-end, box-end, or socket wrench. Ensure mating threads are clean and free of debris before installation. Power down or de-energize any equipment before fastening components in electrical or mechanical assemblies. Do not exceed the load ratings appropriate for Grade 2 steel fasteners in structural applications.
