The use of adhesives is not allowed... but the issue of "loosening" is critical. Introducing the anti-loosening bolt "Motion Tight" that solves the problems of such screws and bolts!

Are you troubled by "looseness of bolts and screws"? MotionTite is a "looseness prevention bolt" that solves your problems with loose bolts and screws. 【Challenges with screws in semiconductor manufacturing】 - I want to eliminate contamination... - I must prevent loosening without using adhesives... - Loosening inevitably occurs due to ultrasonic vibrations... - Bolts break due to ultrasonic vibrations... 【Features of MotionTite】 - Strong loosening prevention power with just the bolt - Fatigue strength increased by 1.2 times - Same workability as regular screws, easily inserted - Stable axial force even without lubricants - Does not seize even with stainless screws - Compatible with sizes from M2.5 to M16 - Achieves weight reduction and cost reduction through bolt downsizing *For more details, please view the materials from [PDF Download] or feel free to contact us.
