Machinists, DIYers, and mechanics – this MaxTool 3/8-16 UNC taper hand tap is a quality tool for creating clean, right-hand threads. It's a standard Unified National Coarse (UNC) thread: 3/8 inch nominal diameter with 16 threads per inch (TPI). The tap is made from premium M2 high-speed steel (HSS), which is tough and offers a long working life. It's a 'taper' tap, which means the first few threads are gradually tapered to help guide it straight and ease the initial cutting, making it great for starting threads in through-holes or even blind holes (though you might need a different style for the very bottom of a blind hole). It has straight flutes and a round shank with a square drive at the top, so you can use it with a standard tap wrench by hand or in a machine if needed. The surface is uncoated, making it versatile for a broad range of materials. Part number HTF02W00R024. A reliable, professional-grade tap from a trusted tool supplier.
