Overview
This fine-thread hex nut is engineered for heavy-duty industrial and construction applications where superior clamping force and joint integrity are non-negotiable. Manufactured from high-grade carbon steel and heat-treated to achieve a Grade 8 classification, it delivers exceptional strength and reliability in high-vibration and high-stress environments. The precise metric fine threading allows for finer adjustment and improved tension control compared to coarse-thread alternatives. A uniform black oxide finish enhances corrosion resistance and provides a clean, professional appearance.
Key Features
Constructed from Grade 8 carbon steel for maximum strength and durability Heat-treated to achieve a minimum tensile strength of 150,000 PSI Fine thread pitch (M20 x 1.5) for superior vibration resistance and precise adjustment Black oxide surface finish for enhanced corrosion protection and a low-glare surface 1.575-inch width across flats ensures compatibility with standard metric wrenches and sockets Fully threaded and chamfered for easier engagement and consistent performance
