Bonded Seal BG Type

Bonded Seal (Washer Oil Seal, Iron Sheet Washer) is a seal that is bonded between iron and rubber. It is applied to a flat surface or a recessed gap threaded hole to increase the tightening performance of the screw, thereby achieving oil resistance, The need for waterproofing. BG has good sealing performance and small tightening torque, so there is no need to use a countersink to center the washer (it is used together with the metric screw of the German standard DIN hexagonal specification).
