Size guide
Every plug is cut face grain and milled to an exact width for a snug, flush fit. Here is how to pick the size, and which sizes each wood comes in.
Choosing a plug size
The size is the plug's width. Match it to the bit that made the hole: your plug cutter, counterbore or Forstner bit. A 3/8" counterbore takes a 3/8" plug. Measure the hole, not the screw.
The width is always exact. The length can vary a little from one production run to the next.
Metric plugs (6, 8 and 10mm) are for metric bits. In dense hardwoods like IPE, Purple Heart, Bloodwood, Sapele and Yellow Balau, use sharp bits for clean holes. Please check your hole size before ordering.

Packs
Plugs come in packs of 10, 25, 50, 100, 250, 500, 1,000 and 2,500. The bigger the pack, the less each plug costs; each product page shows the price per plug.
Dowels
Dowels are consistent in both width and length. For the most accurate fit, drill with a Forstner or brad point bit the same size as the dowel. Please check your hole size before ordering.
