Value Collection MP39068 Hex Cap Screw 3/8-16x5 Grade 8

Product Description

The VALUE COLLECTION MP39068 is a Grade 8 hex head cap screw in a 3/8-16 UNC thread size with a 5-inch length under head. Manufactured from high-strength Grade 8 steel and finished with a zinc yellow dichromate coating for corrosion resistance, this fastener is partially threaded and conforms to ASME B18.2.1 dimensional standards. It is suited for structural and mechanical assemblies requiring a high-strength fastener in inch-standard configurations. Installers across industrial maintenance, mechanical contracting, and equipment fabrication applications commonly use this screw where load-bearing joint integrity is critical.

This cap screw is designed for use in heavy-duty mechanical and structural assemblies where Grade 8 tensile strength is required. The 3/8-16 UNC thread pattern is a common inch-series coarse thread found in fabricated steel structures, equipment mounting, and machinery. The partial thread configuration is typical for through-bolt or clamping applications where a smooth shank is needed in the grip area. Sold in packages of 10, this screw suits both job-site replenishment and shop stock applications.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• 3/8-16 UNC coarse thread for broad nut and tapped-hole compatibility
• Partially threaded shank suits clamping and through-bolt applications
• Conforms to ASME B18.2.1 dimensional standards
• Packaged in quantities of 10 for stock or job-lot use

Compatibility

Designed as a standard inch-series hex head cap screw for use with 3/8-16 UNC threaded nuts, inserts, or tapped holes in steel fabrication, equipment assembly, and mechanical maintenance applications.

Installation Notes

Installation is typically performed by mechanical contractors, millwrights, or maintenance technicians using a standard hex wrench or impact driver with the appropriate socket. Always verify the mating thread is clean and free of debris before assembly. Do not mix with metric fasteners or lower-grade hardware in the same joint. Torque to the Grade 8 specification listed in the applicable engineering standard or job specification for the 3/8-16 thread size.
