Frequently Asked Questions (FAQs)

1. Do I need a special bit to countersink?

For soft woods, like pine, a countersink may not be needed, as you can usually just drill a wee bit longer to get the head flush. But for hardwoods, countersinks are a must if you want the screw head flush, or to hide it completely below the surface by placing wood filler or a plug above it.

2. How do I know what countersink bit to use?

> A simple rule of thumb is to choose a countersink which is 50% larger than the diameter of the hole. > Countersink diameter = 1.5 x Bolt Size (hole) diameter. > Example: For a 1/4-20 bolt, multiply the diameter (. 250) x 1.5 = .
