In the classic game Pin the Tail on the Donkey, players use a push pin to attach the tail to the donkey. On a metal or plastic toy donkey, however, a push pin would be unable to hold the tail in place, especially if it needs to move in some way. A better choice for this application is a solid metal dowel pin.
“Dowel pins are widely used for alignment, but can also work great as a bearing surface for rotation,” explains Mike Apsey, director of product engineering and development at Driv-Lok Inc. “Another benefit is they can be removed and replaced by the end-user without distortion.”
