ROYAL Z BAR WING NUTS
The ROYAL Z Bar cast iron wing nut is used in the formation of walls. They are designed to spin freely on the high speed course Dywidag thread by hand and may be tightened using the length of a hammer. They are available with either a single or double arm. The single arm provides resistance to movement during vibration whereas the balanced double arms make it easier to turn when fitting and removing.
