Standard, Locking, and Washer-Integrated Nuts , Iran

Standard hex nuts are manufactured from Grade 5, 8, or 10 carbon steel per ISO 898-2. Their nominal height is 0.8 times the bolt diameter. Production tolerance class is typically Class B medium or Class C coarse per ISO 4759-1. Locking nuts incorporate vibration-damping mechanisms. The most common type is a nylon insert nut with a PA 6-6 capsule, heat-resistant to 120°C. Metallic types function via elastic deformation or a prevailing torque design e.g., distorted thread. These nuts must retain over 60% of initial clamping torque in standard vibration tests.

Washer-integrated nuts flange nuts feature a monolithic washer with an outer diameter approximately 1.7 times the nominal diameter. The integrated washer thickness typically ranges from 1 to 3 mm. This design improves pressure distribution by up to 40% and protects joint surfaces. For specific applications, slotted castle nuts for cotter pins and closed cap nuts are available. Common anti-corrosion coatings include hot-dip galvanizing, dacromet, and zinc flake. These coatings provide corrosion resistance for 480 to 1000 hours in salt spray testing. All nuts must meet the mechanical and dimensional requirements of ISO, DIN, or ANSI/ASME standards.You can order and buy Standard, Locking, and Washer-Integrated Nuts from Iran by contacting us through whatsaap and email.
