Galvanized Steel Neoprene Sealing Washer thread-pitch-1-75 **If concrete screws are removedGalvanized Steel Neoprene Sealing Washer. Sealing Washers are a thin conically shaped round steel stamping with a centered hole. It is bonded to a rubber neoprene piece slightly smaller in outside and inside diameter. When these washers are assembled with screws the rubber offers a protection against leakage. This reduces the chance of the fastening becoming loose due to vibration, and minimizes damage to the surface for which it is being attached.
