Wide Type That Is Effective When You Want to Reduce the Load of the Mating Material or When You Want to Widen the Ground Contact Area and Ensure a Thread-Locker Effect

Product appearance

Product appearance

  • The wide type with a larger outer diameter is ideal when you want to reduce the load on the mating material, such as when the pilot hole is large, when fastening to a painting surface, or when the mating material is soft, or when you want to widen the ground contact area to ensure a thread-locker effect.
  • Ideal for use with flanged bolts and nuts to optimize load distribution.
  • Fastening with wide washers distributes the tightening load over a wider area and reduces the load on the mating ground.
