Product Details

This product is a Q195 carbon steel pin, a core component for positioning, hinges, and fixing connectors in steel structure engineering. It comes in two classic styles: flat head and round head, both with a standard cotter pin hole at the end for use with cotter pins, providing double anti-loosening for enhanced stability. Made from high-quality Q195 carbon steel through precision turning, polishing, drilling, surface treatment, and dimensional inspection, the pin boasts precise outer diameter dimensions with small tolerances, a smooth, scratch-free surface, and burr-free inner holes. The pin exhibits excellent shear resistance, effectively withstanding shear and tensile forces at steel structure hinges, ensuring precise positioning without displacement. It is suitable for various steel structure supports, railings, steel component hinges, and equipment connector positioning. Each batch undergoes dimensional tolerance and surface smoothness testing, ensuring stable quality and a complete range of specifications. It is an essential positioning fastener for steel structure engineering and hardware assembly.
