Value Collection 97227 Hex Head Cap Screw 1-8x7 Grade 5

Product Description

The VALUE COLLECTION 97227 is a partially threaded hex head cap screw designed for heavy-duty fastening applications in mechanical, structural, and industrial assemblies. Manufactured from Grade 5 steel with a standard uncoated finish, this fastener delivers reliable tensile strength for demanding bolted connections. The 1-8 thread size follows Unified National Coarse (UNC) standards, and the 7-inch length under head accommodates thick material stacks where full-thread screws are not appropriate. It meets ASME B18.2.1 and SAE J429 dimensional and mechanical property specifications. Licensed tradespeople, millwrights, and maintenance technicians routinely use this fastener in equipment assembly and structural repair work.

This cap screw is suited for general-purpose inch-series applications requiring a coarse-thread hex fastener in the 1-inch diameter range. The partial threading is appropriate when the shank must pass through a clearance hole before engaging a tapped bore or nut. It is commonly used in fabrication shops, mechanical rooms, industrial equipment frames, and structural steel connections where Grade 5 strength requirements apply.

Key Features

• Grade 5 steel construction meets SAE J429 mechanical property requirements for medium-strength fastening
• Partially threaded shank allows clearance through stacked material before thread engagement
• 1-8 UNC thread form provides coarse-pitch engagement suitable for general structural use
• 7-inch length under head accommodates thick assemblies and multi-layer material stacks
• Uncoated finish suitable for dry indoor environments or applications where a secondary coating will be applied
• Conforms to ASME B18.2.1 dimensional standards for hex head cap screws

Compatibility

Designed as a standard inch-series UNC hex head cap screw compatible with any tapped hole or hex nut conforming to 1-8 UNC thread specifications per ASME and SAE standards.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician using a properly sized hex wrench, socket, or torque wrench calibrated for the application. Always verify the mating tapped hole or nut matches the 1-8 UNC thread specification before installation. De-energize and lock out any equipment before fastener service per applicable safety regulations. Do not substitute this fastener in applications requiring a higher-grade or corrosion-resistant specification without engineering review.
