Value Collection MP39149 Hex Cap Screw 5/8-11 X 2 in Grade 8

Product Description

The VALUE COLLECTION MP39149 is a fully threaded hex head cap screw designed for high-strength bolted connections in mechanical, structural, and industrial applications. It features a 5/8-11 UNC thread with a 2-inch length under head, manufactured from Grade 8 steel and finished with a zinc yellow dichromate coating for corrosion resistance. Grade 8 is the highest standard SAE grade for inch-series fasteners, making this screw suitable for demanding load-bearing joints. Sold in a package of 10, it meets ASME B18.2.1 dimensional standards. Installation is performed by maintenance technicians, millwrights, and mechanical contractors working on equipment assemblies, structural frames, and heavy machinery.

This screw is suited for residential and commercial mechanical installations requiring high-tensile fasteners in ferrous assemblies. Typical applications include equipment mounting, bracket fabrication, and structural bolting where Grade 8 strength is specified by design or code. The zinc yellow dichromate finish provides moderate atmospheric corrosion protection, making it appropriate for indoor and sheltered outdoor environments. The fully threaded configuration allows maximum thread engagement across the full 2-inch length, which is advantageous in applications requiring clamping through thin or stacked material.

Key Features

• Grade 8 steel construction for high tensile and proof load capacity
• Fully threaded 5/8-11 UNC configuration maximizes thread engagement
• Zinc yellow dichromate finish provides corrosion and wear resistance
• Meets ASME B18.2.1 dimensional standards for hex cap screws
• Sold in a pack of 10 to support multi-fastener jobs

Compatibility

Designed as a standard hex head cap screw for any application calling for a 5/8-11 UNC, 2-inch, fully threaded Grade 8 fastener per ASME B18.2.1.

Installation Notes

Installation is typically performed by qualified mechanics, millwrights, or structural tradespeople. Use the correct hex socket or wrench size for 5/8-inch hex fasteners and apply the torque specified by the equipment manufacturer or applicable structural code. Ensure mating threads are clean and free of debris before assembly. Do not mix Grade 8 fasteners with lower-grade nuts or fittings, as mismatched hardware can compromise joint integrity.
