Frequently Asked Questions

What is the YANKEE Counterbore with Built-In Pilot used for?

The YANKEE Counterbore with Built-In Pilot is used to create a flat-bottomed recess for #4 screw heads in wood or metal. Its built-in pilot aligns the bore precisely, ensuring screw heads sit flush or below the surface. Common in cabinetry, jig building, and general assembly where a clean, countersunk finish is required.

What are the specifications of the YANKEE 301-#4 counterbore?

The YANKEE 301-#4 counterbore has a 13/64 in bore diameter and a 0.112 in pilot diameter, designed specifically for #4 screws. It is a standard built-in-pilot type, manufactured by YANKEE. The part number is 301-#4. These dimensions ensure accurate countersinking without separate pilot bits.

How to select the correct YANKEE counterbore for #4 screws?

The built-in pilot eliminates separate alignment steps. Always verify the screw size and desired countersink depth before ordering the 301-#4 model.
