Pack of 4 Stainless Steel 304 Hexagonal Head Bolt Rods with Double End, Left/Right Threaded Rods with Double End Threaded Rod Bolts, M8 x 50 mm

Features: Strong self-locking: the 304 stainless steel threaded screw adopts hexagonal double head design, and the two ends of the thread direction are opposite (positive and negative teeth), this clever design not only improves the visual effect of the screw, but more importantly, also improves its self-locking performance. The positive and negative thread design ensures uniform force of the screw and can be tightened in both directions at the same time, further improving work efficiency. Easy to install: the hexagonal design of the nut can be well adapted to a variety of open-end wrenches, making the installation and disassembly process more convenient and faster. You can choose the right wrench to work according to your needs and improve work efficiency. When the positive teeth are turned clockwise, the nut moves to the center of the screw; when the negative teeth are turned counterclockwise, it also moves to the center of the screw. This construction allows you to easily adjust the length and degree of tightening of the screw to the actual needs to meet the requirements of different application scenarios. Specification: Material: 304 stainless steel. Package includes: 4 x hexagonal head double end bolt rods.

• Double head design: one end has a left hand thread and the other a right hand thread, allowing the screw to be adjusted or moved in two directions, which provides better self-locking and reduces the risk of loosening in case of vibration or dynamic load
• Hex Shank: The middle part is hexagonal and is suitable for turning and tightening for a standard hex wrench. The distance can be easily adjusted and ensures a stable connection
• Stainless Steel Material The double head bolt is made of high quality stainless steel material, which is corrosion resistant and rust resistant, and is not easily damaged after prolonged use. It offers good wear resistance and mechanical strength
• Easy to use: by turning the screw, the nuts at both ends can move in opposite directions at the same time, making the machine firmly connected
• Wide application: double head screws are suitable for energy, chemical, oil refining, valves, railways, bridges, steel structures, car and motorcycle accessories, machinery, boiler steel structures, crane towers, large span steel structures and large buildings
