Six methods for preventing bolt loosening are outlined: http://www.cmiw.cn/data/attachment/forum/201904/20/101123otpqh1bzlmpf1pb5.gif The best solution for preventing bolt loosening in environments with vibration and frequent impacts. • The wedge-locking technology uses tension rather than friction to secure the bolts. • It ensures proper tightening of fasteners in connections subject to extreme vibration and dynamic loads. • The locking effect is not affected by lubricants. • It can be installed and removed quickly and easily using standard tools. • It has the same temperature characteristics as standard bolts/nuts. • Washers do not affect the reusability of the fasteners. • The washers are hardened to withstand and distribute heavy loads. • It has excellent corrosion resistance. http://www.cmiw.cn/data/attachment/forum/201904/20/101251mkppni72rb872vz2.gif 30° bevel-threaded nuts provide reliable bolt retention. • Their locking performance has been proven through Junkers vibration tests. • These special nuts can be used with ordinary standard bolts. • They are reusable, with even load distribution across the threads, thereby extending the lifespan of both the nuts and bolts. • No additional locking components such as spring washers or stop washers are required. • In addition to the nuts, special taps are available for creating 30° bevel-threaded holes. http://www.cmiw.cn/data/attachment/forum/201904/20/101400fgpigu1pvviisuvd.gif These solutions are widely used in high-speed trains to prevent bolt loosening. • They offer semi-permanent protection. • Tightening is possible even at the middle part of the external threads. • They are reusable and easy to use. http://www.cmiw.cn/data/attachment/forum/201904/20/101407ls6qi638vq338svg.gif They maintain preload under high vibration loads, preventing bolt loosening. • They effectively prevent thread loosening under high vibration conditions. • They have passed rigorous Junkers vibration tests, ensuring safety and effectiveness. • They are particularly suitable for delicate surfaces and soft materials such as aluminum and copper. • They are easy to install and remove, and are reusable. http://www.cmiw.cn/data/attachment/forum/201904/20/101414sjiikjegk4kgpfoo.gif These solutions are ideal for bolts in large or deep holes, offering easy installation. • There is no torsional stress; the stretching of the bolts is purely axial. • Only a handheld torque wrench is needed, with no special tools required. • They are compatible and can be used as replacements for any common nuts of similar strength. • Pressure plates enhance the elasticity of the bolt connection, compensating for deformation and thus maintaining preload. • Improved elasticity reduces dynamic stress on the bolt connection, thereby extending its lifespan. • Friction characteristics are carefully controlled to ensure accurate tightening and repeated tightening. • They are reusable. http://www.cmiw.cn/data/attachment/forum/201904/20/101319j94g0uu11x470o10.gif Reusable forced-locking nuts provide effective bolt retention. • They are reusable without any loss in performance. • They meet the requirements of NAS3350 (**Aerospace Impact Testing Standard**) for 30,000 cycles of accelerated vibration testing. • They are corrosion-resistant and feature a lightweight design

OP, could the picture be clearer and at a slower speed?
