Solve bolt and screw loosening issues with stable axial force! Anti-loosening bolt "Motion Tight" *Workability is the same as regular screws, and it fits smoothly.

Are you troubled by "loose bolts and screws"? Motion Tight is a "loose prevention bolt" that solves your problems with loose bolts and screws. In the aerospace industry and defense military sector, where conditions are extremely strict, such as the inability to use adhesives and the need to minimize contamination, Motion Tight can be applied without any issues. 【Do you have any of these problems?】 ■ Unable to reuse bolts because adhesives are used... ■ Need bolts that won't loosen in areas with a lot of vibration and shaking... ■ Cannot prevent loosening with adhesives because they are used in high-heat areas... ■ Loosening can be prevented on the nut side, but the female thread side has a tapped hole... ⇒ All problems can be solved with the loose prevention bolt "Motion Tight"!
