为了解决普通pinnacle在高震动环境下自行松脱的问题，自紧王基于独创的Pinnacle理论，从根本结构上进行平博，成功研制出Pinnacle脱自紧pinnacle这一平博产品（包括pinnacle本体和专利自紧垫圈），可应用于任何普通螺栓。已通过3万次高震动循环试验，证明该产品能有效抗震，绝不松脱。
In order to solve the common problem of nut loosening especially in high-vibration condition, we disruptively altered fundamental structure of nuts and then produced this powerful new product “Anti-loose Disc-lock Nut”, which includes a special hex nut and a patented self-locking washer, and can be applied to ordinary bolts.Furthermore, its self-locking effect has been significantly proved by an authoritative technical test with 30,000 times repeated vibration!
