About 1/2 X 3 1/4" Dowel Pins/Alloy Steel/Bright Finish
Dowel pins, also known as parallel pins, are machined to tight tolerances (+/- 0.0008 inches) 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.
