Flange Nut
The hex lock nut with washer is a mechanical fastener combining a hex nut and integrated washer, ensuring secure and vibration-resistant connections. Internal diameter typically ranges from M3 to M24, with nut height from 3 to 20 mm. Made from carbon steel or stainless steel A2/A4, tensile strength ranges from 400–800 MPa. The integrated washer, flat or spring type, absorbs tensile force and vibration, preventing loosening under dynamic loads.
Internal threads are precisely manufactured according to ISO or DIN standards, ensuring strong and uniform connections with bolts. Galvanized or chrome coating enhances corrosion and wear resistance. Washers with hex nuts are widely used in metal structures, industrial machinery, construction equipment, and high-vibration mechanical projects. Optimized mechanical design and protective coating extend service life and reduce maintenance requirements.
