Value Collection 451032BR Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 451032BR is a heavy-duty hex head cap screw designed for high-strength bolted connections in industrial, structural, and mechanical assembly applications. Manufactured from Grade 8 steel with a bright uncoated finish, this fastener measures 1-1/4-7 UNC thread size with a 5-inch length under the head and is partially threaded for applications requiring a bearing shank. It weighs 2.25 pounds and conforms to ASME B18.2.1 dimensional standards. The hex drive requires a 1-11/16-inch hex key or wrench. Installation is performed by machinists, millwrights, ironworkers, and maintenance mechanics working on heavy equipment and structural steel assemblies.

This cap screw is suited for high-load bolted joint applications where Grade 8 tensile strength is required. Partial threading provides a smooth shank section for shear-load bearing and precision fit in clearance holes. The uncoated bright finish is appropriate for dry or controlled-environment installations or where a specific plating or coating will be applied post-assembly. Sold individually with a minimum order quantity of 1.

Key Features

• Grade 8 steel construction for high tensile and proof-load strength
• Partially threaded shank suitable for shear-load and precision-clearance applications
• 1-1/4-7 UNC coarse thread form for standard inch-system bolted joints
• Conforms to ASME B18.2.1 dimensional standards
• Bright uncoated finish compatible with post-assembly coating or plating processes
• 1-11/16-inch hex drive for standard wrench or socket tooling

Compatibility

Designed as an OEM-style and aftermarket replacement hex head cap screw for bolted assemblies requiring a 1-1/4-7 UNC, 5-inch, Grade 8 partially threaded fastener per ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or ironworker familiar with high-strength fastener torque procedures. Always consult applicable engineering specifications or fastener torque tables for Grade 8 hardware before final tightening. De-energize and lock out equipment before working on any bolted assembly. Do not reuse fasteners that show signs of thread damage, corrosion, or deformation.
