Value Collection -99245-2 Hex Cap Screw 1-1/4-7 X 4 in Grade 8

Product Description

The VALUE COLLECTION -99245-2 is a Grade 8 steel hex head cap screw sized 1-1/4-7 x 4 inches, supplied in a partially threaded configuration with a Unified National Coarse (UNC) thread form. Manufactured to ASME B18.2.1 standards, this fastener delivers the high tensile strength required for heavy structural, mechanical, and equipment-mounting applications. The uncoated finish suits environments where a specific field-applied coating or plating will be applied after installation. This screw is a standard inch-series fastener used across industrial, commercial, and heavy-equipment assembly work.

This hex head cap screw is suited for bolted connections in structural steel assemblies, heavy machinery, agricultural equipment, and industrial fabrication where Grade 8 strength requirements apply. The partial threading provides a smooth shank section that resists shear loading at the joint interface, making it appropriate for applications where the fastener passes through clearance holes before engaging a tapped member or nut. It is sold in a package quantity of 5.

Key Features

• Grade 8 steel construction for high tensile and proof-load strength
• 1-1/4-7 UNC thread — standard inch coarse-thread series
• 4-inch length measured under the head
• Partially threaded shank provides shear resistance at joint interfaces
• Meets ASME B18.2.1 dimensional standards for hex head cap screws
• Uncoated finish — ready for field coating, plating, or dry use where corrosion is not a concern

Compatibility

Designed as an OEM-style and general-purpose replacement hex head cap screw for heavy structural and mechanical assemblies requiring a 1-1/4-7 UNC, 4-inch partially threaded Grade 8 fastener conforming to ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or structural ironworker familiar with Grade 8 fastener torque requirements for the specific joint design. Always consult the applicable engineering specification or structural drawing for proper torque values — do not estimate. Use a calibrated torque wrench and confirm thread engagement is clean and free of debris before final tightening. Grade 8 fasteners must not be substituted with lower-grade hardware in load-bearing or safety-critical connections.
