• Double-head Design: One end is left-handed thread and the other end is right-handed thread, so that the screw can be adjusted or moved in two directions, providing better self-locking performance and reducing the risk of loosening under vibration or dynamic load
• Hexagonal Shaft: the middle part is hexagonal, suitable for standard hexagonal wrench for rotation and tightening, easy to adjust the distance and ensure a stable connection
• Stainless Steel Material: The double-headed stud is made of high-quality stainless steel material, which is corrosion-resistant and rust-resistant, and is not easy to damage after long-term use, providing good wear resistance and mechanical strength
• Easy to Use: by rotating the screw, the nuts at both ends can move in opposite directions at the same time, which is used to firmly connect the machine
• Wide Application: double-headed screws are suitable for power, chemical, oil refining, valves, railways, bridges, steel structures, automobile and motorcycle accessories, machinery, boiler steel structures, crane towers, large-span steel structures and large buildings

Feature: 【Stainless Steel Material】The hexagonal double-ended screw is made of 304 stainless steel, which is not only hard and wear-resistant, but also able to maintain its integrity in a high-intensity working environment and not easily damaged. And it also has good anti-corrosion and rust resistance, even if used for a long time in a humid or corrosive environment, it can effectively prevent the screw from rusting or being seriously corroded, so as to extend its service life. 【Strong Self-Locking】The 304 stainless steel thread screw adopts hexagonal double-head design, and the two ends of the thread direction is opposite (positive and negative teeth), this clever design not only enhances the visual effect of the screw, but more importantly, also enhances its self-locking performance. 【Firmly Connection】The screw is patiently processed, and each thread is fine and even, which not only improves the strength and durability of the screw, but also makes this hex head double end studs rod more tightly connected without gaps. The fine thread design allows the screw to be firmly locked in the connecting parts after tightening, effectively preventing the loosening phenomenon caused by vibration or external impact. 【Easy to Install】The hexagonal shape design of the nut can be well adapted to a variety of open-ended wrenches, making the installation and disassembly process more convenient and quicker. You can choose the right wrench to operate according to your needs and improve work efficiency. When the positive teeth are turned clockwise, the nut will move towards the center of the screw; when the negative teeth are turned counterclockwise, it will also move towards the center of the screw.
