4Pcs 304 Stainless Steel Hex Head Double Ended Threaded Rod Left/Right with Double Ended Threaded Bolts (M8 x 70mm)

Features: STRONG SELF-LOCKING - The 304 stainless steel threaded screw adopts the double-headed hexagonal design, and the two ends of the thread seal are opposite (positive and negative teeth), this intelligent design not only enhances the visual effect of the screw, but, most importantly, it also improves the self-locking performance. The positive and negative thread design ensures uniform screw strength and can be tightened in both directions at the same time, further improving work efficiency. EASY TO INSTALL - The hex nut design can be adapted well to a variety of keys, so that the installation and disassembly process is more convenient and fast. You can choose the right key to work according to your needs and improve work efficiency. When the positive teeth are rotated clockwise, the nut moves towards the center of the screw; when the negative teeth are rotated counterclockwise, it also moves to the center of the screw. This design allows you to easily adjust the length and degree of tightening of the screw according to actual needs to meet the needs of different application scenarios.
