Multi Groove Fluted Pins

We offer a wide variety of multi-groove pins. Multi-groove pins are also known as fluted pins. Multi-groove pins feature parallel grooves that extend the length of the pin. These parallel grooves allow air and excess glue to escape the hole which makes insertion easier and eliminates blowouts. Our pins are available either plain or pre-glued. We are proud to offer a selection of FSC certified pins that are tracked throughout the manufacturing cycle to ensure sustainability.

    Metric Fluted Pins - Pre-Glued

    Cincinnati Dowel is proud to offer the AquaPin Pre Glued Dowel Pin. The AquaPin is a premium pre glued pin that offers superior diameter tolerance and glue strength.

    What are pre-glued pins? Pre-glued pins start with the same high quality Birch dowel pins you have come to expect. We then use a special process to apply a custom glue that is dyed with a non staining dye which allows you to monitor glue coverage on every pin. Our specially formulated glue reactivates with water eliminating the need for glue to be inserted in the hole.

    Diameter Tolerance: +/- .005"
    Length Tolerance: +/- 1/32"
    Moisture Content: 6%-8%
    Glue Color: Teal

    Benefits of pre glued pins: 
    1.) Can be used in all types of automatic inserting equipment as well as hand use.
    2.) Minimal clean up. No clogging of automatic inserting equipment.
    3.) 100% Glue coverage with no excess glue.
