Spiral Groove Alloy Steel Pull Dowels: Pull, alloy steel spiral groove, pins used in blind hole applications. Dowel pins, also known as parallel pins, are machined to tight tolerances and often used as precise locating devices in machinery. While a wide variety of specifications exists, ANSI B18.8.2 is the most common specification requested in the United States. A solid headless straight pin with a closely controlled diameter. One end is chamfered with the other end radiused to form a crown. Wide variety of uses, including as a plug gage, hinge or shaft. Precise tolerances of dowel pins make them excellent for achieving proper alignment of parts in high-speed assemblies, or as roller bearings in bus/truck wheel housings. Dowel pins are precisely shaped to keep machine type components in pin-point alignment; also used as location guides. Important Note: Dowel pins should be installed by being pressed in, not struck with an impact force.
