  TOMOE KOGYO

  Nut comprises a metal main body together with a nylon ring (Nylon 66) that functions as a locking mechanism. (Fine)
  [Features]
  · Nylon 66 provides high rigidity, heat resistance and wear resistance, and also possesses excellent elasticity.
  · Nylon 66 maintains performance even under conditions that would be extreme for metals, and will not corrode like metals.
  · The internal diameter of the nylon ring is designed to standard to be the same dimension as the effective diameter of the nut's screw thread.
  · An external thread is formed to adhere closely to the nylon ring by fitting together with the external thread of the bolt, generating fitting friction in that portion.
  · This friction generates torque that prevents loosening of the nut caused by rotational vibration, linear vibration and impact, etc. applied from all directions.
  [Applications]
  · Aircraft, highway sound insulation walls, boats, etc.
