Value Collection MP39385 Hex Cap Screw 7/16-20 X 2-1/2 in Grade 8

Product Description

The VALUE COLLECTION MP39385 is a 7/16-20 hex head cap screw engineered for high-strength fastening applications. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this screw delivers superior tensile strength and corrosion resistance compared to lower-grade hardware. The partial threading design provides a clamp load advantage in through-bolt and bolted-joint assemblies. It conforms to ASME B18.2.1 dimensional standards, making it a reliable choice for mechanics, millwrights, and maintenance technicians working on structural, mechanical, or industrial equipment assemblies. Sold in a pack of 10.

This fastener is suited for general industrial and mechanical assembly applications where high-strength, fine-thread fasteners are required. The 7/16-20 UNF thread pitch offers tighter thread engagement than coarse-thread equivalents, making it appropriate for vibration-prone environments or precision-fit joint assemblies. Typical uses include heavy equipment fabrication, automotive drivetrain components, machinery frames, and structural bolted connections requiring Grade 8 load ratings.

Key Features

• Grade 8 steel construction for high tensile and proof-load strength
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• 7/16-20 UNF fine thread for superior clamp load and vibration resistance
• Partially threaded shank for accurate bolt-joint clamping
• Conforms to ASME B18.2.1 dimensional standards
• Sold as a 10-piece pack with a minimum order quantity of 1

Compatibility

Designed as an ASME B18.2.1 conforming hex head cap screw suitable for use with standard 7/16-20 UNF threaded nuts, inserts, and tapped holes in inch-measurement mechanical and structural assemblies.

Installation Notes

Installation is typically performed by mechanics, millwrights, or maintenance technicians using a standard hex wrench or socket set. De-energize and lock out all equipment before fastener installation or removal per applicable OSHA lockout/tagout procedures. Use a calibrated torque wrench and consult the applicable equipment service manual or engineering specification for required torque values, as they are not defined by the fastener grade alone. Do not mix inch and metric hardware in the same joint assembly.
