About this item

  • Fits Bolt Size：M4, Size: 4mmx1mm/0.16inchx0.04inch(OD x T)
  • 304 Stainless steel for corrosion resistance, for outside applications, easy to install.
  • Spring washers are a left-hand helix and allow the thread to be tightened in a right-hand direction only.
  • Apply for electrical connections on household and commercial appliances and industrial products, in order to prevent screw loosening or disperse pressure.
  • The benefit of spring lock washers lies in the trapezoidal shape of the washer. When compressed to loads near the proof strength of the bolt, it will twist and flatten. This reduces the spring rate of the bolted joint which allows it to maintain more force under the same vibration levels. This prevents loosening.
