Value Collection MP39133 Hex Head Cap Screw 9/16-12x2 Grade 8

Product Description

The VALUE COLLECTION MP39133 is a fully threaded hex head cap screw designed for heavy-duty fastening applications requiring high tensile strength. Sized at 9/16-12 UNC thread by 2 inches under the head, this fastener is manufactured from Grade 8 steel with a zinc yellow dichromate finish for corrosion resistance. It conforms to ASME B18.2.1 and SAE J429 standards, making it a reliable choice for structural, mechanical, and industrial assembly work. Licensed tradespeople and maintenance professionals working on equipment, machinery, or structural connections rely on Grade 8 hardware where standard fastener grades fall short.

This screw is suited for high-load fastening scenarios in industrial maintenance, OEM equipment assembly, and mechanical repair. The 9/16-12 UNC thread pattern is a common coarse-thread specification found across heavy equipment, agricultural machinery, and industrial fabrication. The fully threaded design maximizes thread engagement throughout the clamped joint, which is particularly useful in shorter-grip applications where partial threading would reduce holding strength.

Key Features

• Grade 8 steel construction for high tensile and proof load requirements
• Fully threaded 9/16-12 UNC coarse thread for maximum thread engagement
• 2-inch length measured under head for precise fitment in standard applications
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• Meets ASME B18.2.1 and SAE J429 standards for dimensional and mechanical compliance
• Sold in a package quantity of 5

Compatibility

Designed as a standard 9/16-12 UNC fully threaded hex head cap screw suitable for Grade 8 fastener applications in industrial, mechanical, and structural installations.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance professional familiar with proper fastener torque procedures for Grade 8 hardware. Always clean and inspect mating threads before installation. Use a calibrated torque wrench and refer to the applicable engineering specification or equipment service manual for the correct torque value for this thread size and grade. Do not mix Grade 8 fasteners with lower-grade nuts or tapped holes not rated for the corresponding load.
