Overview

This Grade 8 carbon steel hex flange nut is engineered for high-strength, permanent fastening in demanding mechanical and structural assemblies. It combines a standard hex body with an integrated, washer-style flange that distributes clamping force over a wider area, reducing surface pressure and improving joint integrity. The M20 coarse thread ensures robust engagement with compatible bolts, while the black oxide finish provides a baseline defense against corrosion. Manufactured to DIN 6331 specifications, this nut is a reliable component for applications requiring a secure, vibration-resistant connection.

Key Features

Constructed from high-strength Grade 8 carbon steel for superior load-bearing capacity Integrated flange acts as a built-in washer, eliminating the need for a separate component Wide bearing surface helps prevent loosening under dynamic loads and vibration Black oxide finish offers a durable, corrosion-resistant layer for general protection Coarse M20 thread design facilitates easier and faster assembly in industrial settings
