Hex Flange Lock Nuts Serrated Grade 8 Steel Zinc Yellow 3/4-10 are engineered for maximum security in heavy-duty assemblies. The combination of a hex head, a round flange, and a serrated bearing surface ensures even load distribution and reliable locking under vibration.

Key Features

• High-strength Grade 8 steel for durable, long-lasting performance
• Serrated bearing surface helps prevent loosening under dynamic loads
• Flanged hex design distributes clamping force over a larger area to protect mating surfaces
• Zinc Yellow finish provides corrosion resistance and easy identification
• Coarse thread size 3/4-10 UNC for common heavy equipment applications

Design and Benefits

Designed as a lock nut with a built-in flange, these fasteners minimize loosening due to vibration and dynamic forces. The serrated underside grips the mounting surface, while the hex head allows for quick installation with standard wrenches.
