This Spring Hook with Eye Bolt is a multi-functional fastener, produced by Shandong Yifa Casting and Forging. 

The main body is made of metal material (commonly stainless steel or galvanized steel), featuring both corrosion resistance and high strength. 

Its core structure includes a spring-triggered latch and an eye pin with threads. 

The latch allows for quick opening and closing with one hand, while the eye pin can be directly screwed into the base material such as wood or sheet metal, achieving the dual functions of "tool-free fixation + quick connection". 

It is widely applicable in scenarios such as cable rope fixation on ships, outdoor equipment mounting, and home product connection, providing both convenient operation and reliable connection.
