Japanese KFC Launched Sales of K/KP Torque Shear Nut

KFC launched sale of K/KP Torque Shear Nut in August which is a type of torque management nut for preventing human errors. The resin cap free spins when the specified torque is reached, making it possible to confirm the state of fastening with bare eyes.
 
The product has a two-piece structure where a resin cap covers on top of the anti- loosening nut. The operator uses an impact wrench and starts fastening from the top of the resin cap, and when the specified torque is reached the cap free spins and falls off. Accordingly the operator can quickly tell if there is an error with bare eyes.
