Value Collection -97257-1 Hex Head Cap Screw Grade 5

Product Description

The VALUE COLLECTION -97257-1 is a partially threaded hex head cap screw designed for heavy-duty fastening applications across industrial, mechanical, and structural assemblies. Manufactured from Grade 5 steel with an uncoated finish, this fastener features a 1-1/2-6 UNC thread size and a 4-1/2 inch length under head. It meets ASME B18.2.1 and SAE J429 standards, making it a recognized choice for engineers and tradespeople who require a dimensionally consistent, load-rated fastener in inch-system applications.

This hex head cap screw is suited for use in general mechanical assemblies, equipment manufacturing, structural steel connections, and maintenance repair operations. The partially threaded shank provides a smooth bearing surface in the grip area, which is important in shear-load applications or where joint clamping is critical. Installers working in HVAC equipment mounting, pump and motor assembly, and heavy fabrication will find this a commonly specified fastener size for large-diameter bolted connections.

Key Features

• 1-1/2-6 UNC thread size for large-diameter, high-load fastening
• 4-1/2 inch length under head for deep-reach or thick-stack applications
• Partially threaded shank provides clean grip area and shear resistance
• Grade 5 steel construction meets SAE J429 mechanical property requirements
• Uncoated finish suitable for use where additional coatings or thread lubricants will be applied in the field
• Conforms to ASME B18.2.1 dimensional standard for hex head cap screws

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 1-1/2-6 UNC tapped holes and nuts per ASME B18.2.2 specifications in general industrial and mechanical applications.

Installation Notes

Installation should be performed by a qualified mechanic or trades professional using the appropriate hex socket or open-end wrench sized for a 1-1/2-6 fastener. Always clean and inspect mating threads before installation and apply thread lubricant or anti-seize compound as required by the application. Torque to the value specified by the equipment manufacturer or applicable engineering standard for Grade 5 fasteners at this diameter. De-energize or lock out equipment per applicable OSHA lockout/tagout procedures before performing any bolted assembly work on machinery.
