1/2" UNC HSS Die Nut 5060420 0 x 40 Metric CoarseDie nuts are suitable for repairing damaged or crossed threads or clearing swarf from threads. When using a die nut it is not necessary to apply the same level of precise initial alignment required to form a new thread (i. e. with a die) as the nut will follow the existing threads. They are supplied as hexagon allowing them to be turned by a standard spanner or adjustable wrench without the need for a die stock.
