Value Collection 451350BR Hex Head Cap Screw 1-8x16 Grade 8

Product Description

The VALUE COLLECTION 451350BR is a heavy-duty hex head cap screw designed for high-strength bolted connections in structural, industrial, and mechanical assemblies. Manufactured from Grade 8 steel with a bright uncoated finish, this fastener meets ASME B18.2.1 dimensional standards. The 1-8 thread size follows Unified National Coarse (UNC) specification, and the 16-inch length under head is partially threaded, making it well suited for clamping applications where an unthreaded shank is required to bear shear loads. At 3.7 pounds, it is a substantial fastener appropriate for heavy fabrication and infrastructure work.

This cap screw is used in heavy equipment manufacturing, structural steel fabrication, industrial machinery assembly, and maintenance applications where Grade 8 tensile strength is specified. The partially threaded shank provides a grip length that resists shear forces in bolted joints. Licensed trades and industrial assembly technicians working with large-bore fasteners will encounter this size in OEM equipment builds, field repairs, and custom fabrication projects.

Key Features

• Grade 8 steel construction for high tensile and proof load ratings
• Partially threaded shank provides shear-resistant grip length
• 1-8 UNC thread form for broad hardware compatibility
• Bright uncoated finish - suitable for applications where coating is not required or will be applied after installation
• Meets ASME B18.2.1 dimensional standard
• 1-1/2 inch hex key drive size for standard heavy-duty impact and torque tooling

Compatibility

Designed for use in any bolted assembly specifying a 1-8 UNC hex head cap screw with a 16-inch length under head and Grade 8 steel per ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or ironworker using appropriate torque tooling rated for Grade 8 fasteners of this size. Always consult the equipment manufacturer's torque specifications and applicable structural or mechanical codes before final tightening. Inspect mating threads and seating surfaces for damage before assembly. Do not use impact tools alone for final torque - verify with a calibrated torque wrench.
