Internally Threaded Taper Pins 7978


Internally Threaded Taper Pins are round pins that the diameter uniformly increases along the length of the pin and has an internally threaded hole at the large end.

Internally Threaded Taper Pins are used in tapered holes where there is only access to one side of the hole. They can be used to aid in critical alignments since the small end of the pin is inserted first it can pass into a hole that is not exactly aligned and as the diameter of the pin increases it forces the two holes to become exactly aligned. Threaded Taper Pins can also be used on assemblies that are expected to be disassembled and reassembled more frequently since they are generally easier to install and remove than dowel pins or spring tension pins. Internally Threaded Taper Pins are removed by screwing an extraction tool into the thread of the pin and applying leverage.

Metric & Multistandard Components Corp. supplies DIN 7978 Internally Threaded Taper Pins. DIN 7978 Internally Threaded Metric Taper Pins have a 1:50 taper which means that for every 50mm in length the diameter increases by 1mm. The nominal size is the diameter of the small end on the pin.
