Why Sprial Grooved Dowel pins?
The dowel pins are grooved in a spiral pattern running down the full length of the wood pin. The spiral pattern assures proper application of the glue.
Benefits of Sprial Grooved Dowel Pins
- The multiple grooves are more forgiving when pressed into the dowel hole, providing less stress on the wood joint and reducing the risk of splitting.
Features of Sprial Grooved Dowel Pins
DOWEL ENDS: All of our spiral grooved dowel pins come with ends which are chamfered for ease of insertion. The tapered leading edge is designed to easily drive into the hole.
KILN DRIED: Spiral Grooved Dowel Pins should always be kiln dried instead of air dried to ensure the pin won't distort.
WOOD TYPE: Hardwood Spiral Grooved Pins. Because wood working projects require dowel pins to resist shrinkage.
QUALITY: The Spiral Dowel is precision made with a tolerance of . 005 for a very tight fit in the properly drilled dowel hole.
Sprial Grooved Dowels VS STANDARD Dowels
Why Spiral Grooved over a standard dowel pin?
Spiral grooved dowel pins are considered to be some of the strongest due to the amount of wood that presses against the sides of the hole that the sit in.

FAQ'S
What Size of Dowel Pin should I use?
What should be the right length Spiral Grooved pin? What makes a dowel stronger? The rule of thumb is the longer the dowel the stronger the joint. Also the diameter of a spiral grooved dowel should not be more than 1/2 of the thickness of the wood.
What Size should the hole be?
To assure the dowel pin will fit snugly into the hole for your project, do not drill a hole size more than 1/8" longer than the dowel pin.
How should the dowel pin be inserted?
The dowel can be manually inserted using a light tap with a rubber mallet.
Should you apply glue?
Filling the hole with standard wood glue before dowelling will provide excellent glue dispersion throughout the grooves of the spiral dowel and create a lasting bond. For better results, after gluing this dowel pin into place use a clamp to hold the wood together. This will prevent the wood from splitting around the hole due to pressure.
TIPS
-— Tip 1 -—
Multiple spiral dowel pins can be used to strengthen a joint. As a rule of thumb, the heavier the weight of the two wood components, the more dowels should typically be used.
-— Tip 2 -—
After inserting your dowel pins into the joints, clamp and allow to dry for 24 hours
-— Tip 3 -—
Some shops even place their dowel pins in an oven. They do this so that after inserting the dowel, it will fit snugly in the hole with the glue when the project is finished.
