Value Collection 451198BR Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 451198BR is a Grade 8 steel hex head cap screw with a 1-14 UNF thread and a 9.5-inch length under the head. It is partially threaded and supplied in a bright, uncoated finish. This fastener is manufactured to ASME B18.2.1 standards, making it a reliable choice for high-strength bolting applications in mechanical, structural, and industrial assemblies. The 1-1/2-inch hex key size accommodates standard heavy-duty wrenching. At 2.3 pounds, this is a substantial fastener suited for heavy-load joints where tensile strength and shear resistance are critical requirements.

This cap screw is used in heavy-duty mechanical and structural applications where Grade 8 strength is required. Typical installations include industrial machinery, equipment mounting, structural steel connections, and fabrication assemblies. The partial thread design allows for precise clamping force distribution across the unthreaded shank, which is particularly important in shear-loaded joint configurations. It is commonly selected by millwrights, maintenance mechanics, and fabricators working on ferrous metal assemblies that demand a high-strength inch-series fastener.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 1-14 UNF thread provides fine-pitch engagement for precise torque control
• Partially threaded shank distributes shear loads across the grip length
• Bright uncoated finish suitable for use with separate anti-corrosion treatments or in dry indoor environments
• Meets ASME B18.2.1 dimensional standards for hex head cap screws
• 1-1/2 inch hex drive size compatible with standard heavy-duty sockets and wrenches

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 1-14 UNF Grade 8 fastener with a 9.5-inch length under the head per ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with high-strength fastener torque requirements. Always consult the applicable joint design specification or engineering documentation for the correct torque value before installation. Ensure mating threads are clean and free of debris before assembly. Grade 8 fasteners must not be substituted with lower-grade hardware in structural or safety-critical joints.
