About this item: 12 x 1.25mm MF Chrome Die Nut Metric Fine. Die nuts are commonly used when a button die is not suited due to work space restrictions and / or on site thread accessibility. They can be used as thread chasers to clean an existing thread. They can also be used to create a new male thread on non-ferrous metals and plastics. Chrome alloy dies are not suitable for creating precision, safety or critical threads. Metric Fine button dies and die nuts have a 60º angle of thread. The crest is flat and the thread has clearance at the root allowing external thread and internal thread to engage well. Larger root radius and lower thread height enable easy screw thread processing and increase thread screw strength. The major diameter of external thread and pitch are specified by a simple numerical value (most commonly measured in millimeters).
