The process of cutting the threads in a hole is called "tapping" the hole.
Guhring offers a full range of taps for the creation of internal thread forms.
Coarse Thread Series UNC & Metric M is the most commonly used thread system
in the majority of screws, bolts and nuts. The UNC coarse thread is often used
for quick assembly or disassembly. Fine Thread Series UNF & Metric Fine MF is
used for applications that require higher tensile strength than the coarse
thread series and where thin walls are required.
Using only premium substrate materials such as cobalt, powdered metal cobalt and
carbide, Guhring taps are designed to last longer and provide high quality
thread results. Guhring taps are produced to both ANSI and DIN specifications
for a variety of applications. The color ring system allows the end user to
quickly choose the correct tap style for the material that is being threaded.
