Whether you're trying to hide the fact you have used pocket hole screws, or make it obvious with a contrasting species of timber, the Kreg plugs make this possible. These are solid wood plugs, can be trimmed to length and are designed for timbers 1/2" to 1-1/2" thick.
Seven varieties available. Not available for the HD jig.
Micro Solid Wood Pocket Hole Plugs - Paint Grade - 65pcs
For use with any timbers when they are to be painted, so the plugs will not be seen.
Suitable only for the Kreg Jig Micro Drill Guide System, this system does fit to all K5, K4 and K3 models.
