Value Collection MSC-67472241 Hex Nut 7/16-20 Grade 8

Product Description

The VALUE COLLECTION MSC-67472241 is a Grade 8 steel hex nut with a 7/16-20 UNF thread size and a black oxide finish. Grade 8 steel provides high tensile strength for demanding fastening applications where standard hardware-grade nuts would be insufficient. The black oxide coating offers mild corrosion resistance and a low-reflectance surface. At 0.6875 inches across the flats and a right-hand thread, this nut is sized for standard 7/16-inch fastener assemblies. Licensed tradespeople and assembly technicians use this nut in structural, mechanical, and equipment-mounting applications that specify Grade 8 hardware.

This hex nut is suited for high-strength bolted connections in industrial, automotive, and heavy equipment assembly. The 7/16-20 fine thread specification provides greater thread engagement and improved resistance to loosening under vibration compared to coarse-thread equivalents. Right-hand thread direction is standard for the vast majority of mechanical assemblies. The black oxide finish makes it a practical choice when bare zinc or bright finishes are not acceptable on visible or high-cycle joints.

Key Features

• Grade 8 steel construction for high-strength, high-load fastening applications
• 7/16-20 UNF fine thread for improved vibration resistance and thread engagement
• Black oxide finish provides mild corrosion resistance and a low-reflectance appearance
• Right-hand thread direction compatible with standard bolt and stud assemblies
• 0.6875 inches across flats fits standard 11/16-inch hex wrench or socket

Compatibility

Designed as a standard replacement or service hex nut for any bolted assembly specifying a 7/16-20 UNF Grade 8 fastener with an 11/16-inch wrench flat.

Installation Notes

Installation should be performed by a qualified mechanic or assembly technician familiar with torque specifications for the parent assembly. Always power down or de-energize equipment before accessing fastener locations in electrical or mechanical enclosures. Use a calibrated torque wrench and follow the torque values specified by the equipment manufacturer for Grade 8 fastener assemblies. Do not mix thread standards or grades within the same fastener joint.
