Overview
This Grade 8 carbon steel hex nut is engineered for high-strength, fine-threaded bolting applications where superior clamping force and long-term reliability are critical. The M56-4 fine thread pitch allows for precise adjustment and a more secure, vibration-resistant connection compared to standard coarse threads. Featuring a durable black oxide finish, this nut provides a protective layer against corrosion in demanding industrial environments. Each package contains six nuts, providing a convenient supply for assembly and maintenance projects.
Key Features
Manufactured from high-strength Grade 8 carbon steel for exceptional durability and load-bearing capacity. M56-4 fine thread design enables precise tensioning and offers enhanced resistance to vibrational loosening. Protective black oxide finish provides a measure of corrosion resistance and a clean, professional appearance. Precision-machined for consistent thread engagement and reliable performance in critical assemblies. Width across flats of 2.20 inches allows for secure application of standard wrenches and sockets.
