Product Description

The internal & external thread bolt is a special and versatile fastener independently developed and produced by Zhejiang Tianhong Fasteners Co., Ltd. It integrates both internal (female) thread and external (male) thread structures in one component, which is a clever design that enables flexible connection between different parts and materials. Different from ordinary single-thread bolts, this product can realize the conversion and extension of connection functions—its external thread can be matched with nuts or threaded holes, while the internal thread can be connected with screws or studs, effectively solving the connection problem of different threaded specifications or component types. Manufactured by advanced cold processing technology and high-quality raw materials, the bolt has precise thread specifications, uniform pitch, and strong wear resistance, ensuring tight fitting and stable operation in long-term use without loosening easily even under vibration conditions. It is widely used in electric meters, electrical equipment, electronic products, auto parts, renewable energy industry and other fields, providing reliable connection solutions for various mechanical and electrical assembly scenarios.
