steel washers resist moisture, chemicals, and friction and are good electrical insulators. These have a large surface that distributes holding pressure to reduce the likelihood of crushing insulation.
steel Washers with an insulating seal have a stiff center with a flexible perimeter that creates a barrier against air and moisture penetration when fastened to rigid insulation.
