These pins are machined from aluminum and specifically designed for modelers building working components, linkages, suspensions or simply the need for the finest of details. They are scaled down nuts and bolts (without threads) to hold these linkages in place.
Simply slide bolt through linkage and affix nut. These pins easily take the place of any large or odd looking pin you have in mind and will look like the real thing. Their applications are only limited by your imagination.
