Value Collection 403324BR Hex Head Cap Screw 7/8-9

Product Description

The VALUE COLLECTION 403324BR is a partially threaded hex head cap screw designed for general-purpose fastening applications across mechanical, structural, and industrial assembly work. Built to Grade 2 steel specifications with a zinc-plated finish, this fastener measures 7/8-9 thread size with a 4-1/2 inch length under head, following Unified National Coarse (UNC) thread standards. The zinc plating provides a baseline level of corrosion resistance suitable for indoor and light-duty outdoor applications. Tradespeople and assembly technicians reach for this fastener when a strong, reliable threaded connection is needed without the overhead of higher-grade alloy hardware.

This screw is suited for residential and commercial construction, mechanical equipment assembly, and general maintenance work where Grade 2 steel meets load and shear requirements. The partial threading allows for greater clamping force across unthreaded shank sections, making it appropriate for bolted joint assemblies where the shank spans multiple material layers. A 1-5/16 inch hex key drive size allows use with standard wrenches and sockets widely found in trade toolkits.

Key Features

• 7/8-9 UNC thread size for broad compatibility with standard inch-system nuts and tapped holes
• 4-1/2 inch length under head for deep fastening applications
• Partially threaded shank for improved clamping force in multi-layer joints
• Grade 2 steel construction provides adequate tensile strength for general-purpose fastening
• Zinc-plated finish for basic corrosion resistance in light-duty environments
• 1-5/16 inch hex drive size compatible with standard open-end, box, and socket wrenches

Compatibility

Designed for use with standard 7/8-9 UNC inch-system nuts, washers, and tapped holes in general mechanical and structural fastening applications.

Installation Notes

Installation is performed with a standard 1-5/16 inch open-end, box, or socket wrench. Verify that mating threads are clean and free of debris before assembly to prevent cross-threading. Always confirm the fastener grade meets the load requirements of the application before installation. Follow applicable mechanical and structural codes for proper torque and joint design.
