Solving the loosening problem of small-diameter screws under 3mm: 'Loosening Prevention Screws and Bolts'

Are you troubled by the loosening of small screws and small diameter screws? We improve the problem of "loosening" without using adhesives.

Motion Tight is a "looseness prevention bolt" that solves the problem of loosening bolts and screws. Its workability is the same as that of regular screws, allowing for smooth insertion and demonstrating a stable axial force that effectively prevents loosening. While it is a highly versatile small-diameter screw, using adhesives becomes difficult for sizes below 3mm, making the loosening issue a chronic challenge. ⇒ However... with Motion Tight? It can accommodate sizes of '2mm, 2.5mm, and 2.6mm', making it effective for preventing loosening in small-diameter screws! 【Product Features】 ■ Strong loosening prevention power with the bolt alone ■ Fatigue strength 1.2 times greater ■ Workability is the same as regular screws, allowing for smooth insertion ■ Stable axial force even without lubrication ■ Does not seize even with stainless screws ■ Prevents loosening without using adhesives (no contamination occurs) *For product details, please view the materials from [PDF Download] or feel free to [Contact Us].
