Pull Out Dowel Pins or just Pull Dowels are sometimes called Threaded Dowel Pins or just Threaded Pins, and can be either internally threaded or externally threaded, and sometimes tapered. The purpose of the thread, however, is to enable the pin to be removed once a suitable pull attachment has been screwed on.
Threaded Pins Diameters
Threaded Pins are available on the FCH Network with Imperial/US diameters that range from #1 to 5 and with Metric diameters that range from M4 to M40. The length of Threaded Pins is usually measured from the point to the underside of the head.
