Value Collection 97223 Hex Head Cap Screw 1-8x5 Grade 5

Product Description

The VALUE COLLECTION 97223 is a partially threaded hex head cap screw designed for general mechanical fastening in structural and industrial applications. Built to Grade 5 steel standards, this fastener delivers reliable tensile strength for bolted joint assemblies. The 1-8 thread size follows UNC (Unified National Coarse) specification, and the 5-inch length under head suits through-bolting in medium to heavy-gauge material stacks. The uncoated finish means this screw is intended for dry or protected environments, or for use where a field-applied coating or lubricant will be specified by the installer. Conformance to ASME B18.2.1 ensures dimensional consistency across the lot. Sold in packages of 10.

This cap screw is suited for general fabrication, equipment assembly, structural bolting, and maintenance repair in commercial and industrial settings. Typical applications include machinery frames, steel-to-steel connections, support structures, and bracket assemblies requiring a coarse-thread fastener with controlled head geometry. The hex drive is compatible with standard open-end, box-end, and socket wrenches. This fastener is installed by millwrights, pipefitters, general mechanics, and maintenance technicians working across manufacturing, construction, and trade service environments.

Key Features

• Grade 5 steel construction provides mid-range tensile strength for structural bolting applications
• Partially threaded shank allows for shank bearing in clearance holes, improving shear load performance
• 1-8 UNC thread form is a standard coarse-thread pitch compatible with widely available nuts and tapped holes
• Conforms to ASME B18.2.1 for consistent head dimensions and thread tolerances
• Uncoated finish suitable for controlled environments or where field coating is applied
• Sold in packs of 10, with a minimum order quantity of 1 pack

Compatibility

Designed for use with standard 1-8 UNC hex nuts and tapped holes conforming to ASME and UNC thread standards in steel fabrication and general mechanical assembly applications.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance technicians using standard hex wrenches or impact tools rated for the fastener grade. Always ensure the mating nut or tapped hole matches the 1-8 UNC thread specification before assembly. De-energize and lock out any equipment before servicing bolted connections on live machinery. Refer to applicable torque specifications from the equipment manufacturer or a recognized fastener standard for proper clamp load.
