The U-shaped structure anti loosening principatechnology has obtained a national invention patentwith patent numberZL2021 1 0487670.0.
We transfer the position of the vibration force bychanging the structure of the nut, transmitting thevibration force to the top of the nut, forming a cen-tripetal tightening force, achieving the best anti loos-ening effect,andcreatively achieving:
One nut can preventlooseningRepeated installationand never looseningThe vibration strongerthe grip tighterJinmao brandU-shaped anti loosen-ing nuts can beapplied to vibration and anti loosening scenarios and products such asaerospace, national defense and military industry,rail transit, automotive wind power, national powergrid, nuclear power, bicycles, household applianceshigh-end equipment, etc.
