Internally Threaded Dowel Pins
Internally threaded dowel pins are precision alignment pins with chamfered ends and internal threads on one or both sides. They are designed for applications requiring screw-assisted installation or removal, or where pre-positioned threaded holes are needed.
In addition to providing standard locating and stopping functions, these pins are ideal for assemblies that require frequent disassembly or secure fastening.
