Value Collection -99244-2 Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION -99244-2 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It carries a 1-1/4-7 UNC thread size with a 2-1/2 inch length under head, manufactured from Grade 8 steel in an uncoated finish. Grade 8 steel delivers a high tensile strength rating, making this fastener appropriate for heavy-duty bolted joints where fastener integrity under load is critical. It conforms to ASME B18.2.1, the standard governing the dimensional and mechanical requirements for inch-series hex cap screws.

This cap screw is suited for use in industrial machinery, heavy equipment fabrication, structural steel connections, and mechanical assemblies requiring a high-grade inch-series fastener. The fully threaded shank provides thread engagement along the entire bearing length, which is useful in applications where maximum clamping force and thread engagement depth are needed. Maintenance technicians, millwrights, and mechanical contractors working on equipment requiring large-diameter fasteners are the typical installers of this size and grade.

Key Features

• 1-1/4-7 UNC thread size for large-diameter, high-load fastening
• 2-1/2 inch length under head provides substantial grip range
• Grade 8 steel construction for high tensile and proof load strength
• Fully threaded shank maximizes thread engagement throughout the grip length
• Uncoated finish suitable for applications where a coating is applied post-installation or not required
• Conforms to ASME B18.2.1 dimensional standards

Compatibility

Designed as an OEM-style replacement or service fastener for industrial and mechanical assemblies requiring a 1-1/4-7 UNC Grade 8 hex head cap screw conforming to ASME B18.2.1.

Installation Notes

Installation of large-diameter Grade 8 fasteners should be performed by qualified mechanical or structural tradespeople familiar with proper torque procedures for the specific joint material and application. Always ensure mating nut or tapped hole threads are clean and the correct thread class before assembly. Use a calibrated torque wrench and consult the applicable equipment service manual or structural specification for the required torque value. Do not substitute a lower-grade fastener in applications specified for Grade 8.
