Value Collection 451154BR Hex Head Cap Screw 3/4-16 X 8 in

Product Description

The VALUE COLLECTION 451154BR is a Grade 8 steel hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Measuring 3/4-16 thread size with an 8-inch length under head, this partially threaded fastener is manufactured to ASME B18.2.1 standards, ensuring dimensional consistency and reliable torque performance. The bright uncoated finish is standard for Grade 8 applications where post-installation coating or plating may be applied. At 1.1 pounds, this is a substantial fastener suited for heavy-duty bolted connections. A 1-1/8-inch hex key size is required for installation and removal.

This cap screw is used across a wide range of trades and industries requiring high-tensile fastening, including HVAC equipment mounting, mechanical equipment bases, structural steel connections, and heavy machinery assembly. The UNF (Unified National Fine) thread standard provides improved thread engagement and resistance to loosening under vibration compared to coarse-thread fasteners. Partially threaded shanks allow for precise clamping without thread engagement along the full grip length, making this configuration appropriate for through-bolting thick materials or flanged connections.

Key Features

• Grade 8 steel construction for high tensile and proof load requirements
• 3/4-16 UNF thread standard for fine-thread engagement and vibration resistance
• Partially threaded shank for full grip-length clamping
• Bright uncoated finish compatible with secondary coating or plating processes
• Manufactured to ASME B18.2.1 dimensional standards
• 1-1/8-inch hex drive for use with standard industrial wrenches and sockets

Compatibility

Designed as an OEM-style replacement or standard-specification fastener for any application requiring a 3/4-16 UNF Grade 8 hex head cap screw with an 8-inch length under head per ASME B18.2.1.

Installation Notes

Installation should be performed by qualified mechanical or structural trades familiar with fastener torque specifications for Grade 8 hardware. Always consult the applicable torque chart for 3/4-16 Grade 8 fasteners and use a calibrated torque wrench to achieve proper clamp load. Ensure mating threads and bearing surfaces are clean and free of debris before installation. Follow all applicable codes and equipment manufacturer guidelines when incorporating this fastener into structural or pressure-rated assemblies.
