Material: Crafted from high-quality materials (carbon steel Q235, 45#, 304/316 stainless steel, alloy steel 40Cr, 35CrMo), with strict material inspection and professional heat treatment (quenching & tempering) to ensure excellent mechanical performance. It is corrosion-resistant, rust-proof, high-strength, and wear-resistant, suitable for various industrial, construction and mechanical working environments, complying with industrial safety and quality standards.

Size: Standard dimensions comply with GB/T 5782-2016 (equivalent to ISO 4017), with thread specifications ranging from M3 to M64, and bolt length, hexagon head size, thread pitch (coarse/fine) fully customizable as per customer requirements. We offer flexible size options to perfectly match hexagon nuts, plain washers and other fasteners, catering to diverse industrial, construction and commercial demands.

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

Function: Cooperates with hexagon nuts and plain washers to achieve firm fastening of two or more connected parts, effectively transferring and bearing tensile, shear and other loads. It ensures stable connection, prevents loosening caused by vibration, impact or long-term use, protects the connected parts from damage, and extends the service life of the entire fastening system, widely used in various high-load and general 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 5000 pieces.
