Material: Crafted from high-quality materials (carbon steel Q235, 45#, 304/316 stainless steel, alloy steel 40Cr), with strict material inspection to ensure excellent mechanical performance. It is corrosion-resistant, rust-proof, high-strength, and wear-resistant, suitable for various industrial working environments, complying with industrial safety and quality standards.

Size: Standard dimensions comply with GB/T 6170-2015 (equivalent to ISO 4032), with thread specifications ranging from M3 to M64, and thickness, outer diameter fully customizable as per customer requirements. We offer flexible size options to perfectly match different bolts, thread rods and fasteners, catering to diverse industrial, construction and commercial demands.

Features: Boasts a precise hexagonal structure, smooth surface, uniform thickness, no burrs or deformation, and high thread accuracy. It has strong load-bearing capacity and anti-loosening performance, not easy to slip or deform under torque, and supports surface treatment customization (hot-dip galvanizing, electro-galvanizing, nickel plating, passivation) to enhance corrosion resistance and service life.

Function: Cooperates with bolts and thread rods to achieve firm fastening of connected parts, effectively transferring and bearing load. It ensures stable connection, prevents loosening caused by vibration, impact, or long-term use, protects the thread of fasteners, and extends the service life of the entire fastening system, widely used in various fastening scenarios.

MOQ: Minimum order quantity is 5000 pieces for standard items (default material, size, surface treatment). For customized items (custom material, size, thread specification, surface treatment), the minimum order quantity is 100,000 pieces.
