5/16" - 18 UNC Threaded Top Hat Blind Bung
This is a mild steel bung tapped with an imperial 5/16"-18 UNC thread, however the hole is blind which means it does NOT go all the way through. Therefore this bung is ideal for applications where you don't want any leaks, such as fuel and oil tanks. All you have to do is drill a 12mm hole and the bung will sit nice and snug, ready for welding.
