Value Collection C50000152 Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION C50000152 is a heavy-duty hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Built to Grade 8 steel specifications, this fastener delivers superior tensile and proof load strength compared to lower-grade alternatives. It features a 1-1/2-6 UNC thread size with a 5-1/2-inch length under head and a partially threaded shank, conforming to ASME B18.2.1 dimensional standards. The uncoated finish is standard for applications where a secondary coating or plating will be applied on-site, or where bare steel is acceptable for the service environment.

This cap screw is suited for heavy equipment assembly, industrial machinery, structural steel connections, and other applications requiring a reliable, high-strength fastener. The large 1-1/2-inch diameter and partially threaded shank make it appropriate for through-bolt and flange-joint installations where shank bearing load is a design factor. Trades and fabricators working in manufacturing, construction, and maintenance environments commonly specify Grade 8 fasteners like this one for critical load-bearing joints.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 1-1/2-6 UNC thread form per standard Unified National Coarse specification
• 5-1/2-inch length under head for deep through-bolt and flange applications
• Partially threaded shank provides shear resistance at the joint interface
• Conforms to ASME B18.2.1 dimensional standards for hex head cap screws
• Uncoated finish compatible with field-applied plating or coating processes

Compatibility

Designed as a standard-dimension hex head cap screw conforming to ASME B18.2.1, suitable for use with any 1-1/2-6 UNC threaded nut or tapped hole of the appropriate thread class and material rating.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with high-strength fastener torque requirements for Grade 8 hardware. Always use a properly rated 1-1/2-inch hex nut and hardened washer appropriate for the joint design. Verify thread engagement depth meets engineering specifications before applying final torque. Inspect threads for damage or contamination before assembly to avoid galling or cross-threading.
