Value Collection 451147BR Hex Head Cap Screw 3/4-10 X 9-1/2 in

Product Description

The VALUE COLLECTION 451147BR is a Grade 8 steel hex head cap screw with a 3/4-10 UNC thread and a 9-1/2 inch length under head. Partially threaded, it is designed for high-strength fastening applications where a smooth shank is needed along part of the bolt length to resist shear loads or allow clamping without thread engagement in the joint material. At 1.3 pounds, this is a substantial fastener suited to heavy-duty structural, industrial, and mechanical assemblies. It meets ASME B18.2.1 dimensional standards and carries an uncoated, bright finish.

This cap screw is commonly used in structural steel connections, heavy equipment fabrication, machinery frames, and industrial maintenance applications. The 3/4-10 coarse thread pitch makes installation faster and more tolerant of minor thread damage or contamination than fine-thread equivalents. It is a standard choice for maintenance technicians, millwrights, ironworkers, and industrial mechanics working with high-load bolted joints in both shop and field environments.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Partially threaded shank resists shear and allows precise clamping
• 3/4-10 UNC coarse thread for fast installation and field serviceability
• 9-1/2 inch length under head suits deep or stacked material applications
• Meets ASME B18.2.1 dimensional standards for consistent fitment
• Bright, uncoated finish suitable for use with standard plated nuts and washers

Compatibility

Designed for use with 3/4-10 UNC hex nuts and washers in Grade 8 or equivalent high-strength bolted assemblies conforming to ASME B18.2.1 standards.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or ironworker familiar with high-strength fastener torque requirements per applicable standards such as AISC or ASME guidelines. Always pair with a properly rated nut and hardened washer appropriate for Grade 8 hardware. Use a 1-1/8 inch hex wrench or socket to drive this fastener. Inspect threads for damage before installation and do not install if thread profile is compromised.
