3/8" Spiral Pins
Our premium spiral-grooved Birch dowel pins are made from the highest quality Birch lumber. We engineer our pins to a diameter tolerance of +/- .005" with a moisture content of 6-8%.
We recommend applying glue to both the pin and the inside of the hole to ensure even glue coverage.
