Value Collection C50000157 Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION C50000157 is a fully threaded hex head cap screw designed for heavy-duty fastening applications. It features a 1-1/2-6 UNC thread size and a 4-1/2-inch length under head, manufactured from Grade 8 steel in an uncoated finish. Grade 8 steel provides high tensile strength, making this fastener suitable for demanding structural and mechanical assemblies. Manufactured to ASME B18.2.1 standards, it delivers consistent dimensional accuracy expected in professional trade and industrial work. Licensed trades and maintenance professionals rely on this specification for critical bolted connections.

This hex head cap screw is suited for heavy equipment, structural steel connections, machinery assembly, and general industrial fastening where high-strength inch-series hardware is required. The fully threaded shank provides maximum thread engagement along the full grip length, which is advantageous in applications with thin or close-tolerance clamped members. It is commonly used in HVAC equipment frames, mechanical support structures, and industrial fabrication work requiring Grade 8 performance.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Fully threaded shank with 1-1/2-6 UNC thread form for maximum engagement
• 4-1/2-inch length under head suits deep-reach or stacked-member applications
• Meets ASME B18.2.1 dimensional standards for consistent, reliable fitment
• Uncoated finish suitable for applications where coating thickness is a tolerance concern

Compatibility

Designed as an OEM-style replacement or direct-use fastener for applications requiring 1-1/2-6 UNC Grade 8 hex head cap screws per ASME B18.2.1.

Installation Notes

Installation should be performed by qualified mechanics or trades personnel familiar with high-strength fastener procedures. Always power down and de-energize or de-pressurize the equipment or structure before replacing or installing structural fasteners. Use a calibrated torque wrench and follow the applicable equipment manufacturer torque specifications for Grade 8 fasteners of this diameter. Refer to ASME or AISC guidelines as appropriate for the specific application.
