Value Collection 403326BR Hex Head Cap Screw 7/8-9 X 5 in

Product Description

The VALUE COLLECTION 403326BR is a partially threaded hex head cap screw designed for general-purpose fastening in structural and mechanical assemblies. Sized at 7/8-9 UNC thread with a 5-inch length under head, this fastener is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in dry and mildly humid environments. The hex drive measures 1-5/16 inches across the flats for standard wrench engagement. Partial threading allows the unthreaded shank to bear shear loads and align mating components, making this screw a common choice in bolted joint assemblies where precise clamping and load distribution are required.

This fastener is suited for light- to medium-duty applications in fabrication, maintenance, and general industrial assembly. Typical use cases include equipment frames, structural brackets, and utility fixtures where Grade 2 steel meets the strength requirement. It is commonly installed by millwrights, maintenance technicians, pipefitters, and general contractors working on non-critical structural connections. The 7/8-9 UNC thread pattern is a standard coarse-thread designation widely used in inch-based fastener systems across commercial and industrial trades.

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 7/8-9 UNC partially threaded fastener conforming to general Grade 2 steel specifications.

Installation Notes

Installation is performed with a standard 1-5/16 inch open-end, box-end, or socket wrench. Always ensure mating threads are clean and free of debris before assembly. Apply appropriate thread lubricant or anti-seize compound as required by the application. Follow applicable mechanical or structural codes for torque and fastener grade requirements.
