The Drill & Drive bit bores a 3⁄8” hole in which the rim can be adversely affected with the use of a bugle head screw. The diameter of the bugle head screw barely fits in a 3⁄8” hole, and when driven in, it can create an oblong area at the rim of the plug hole leaving room for moisture intrusion after the plug is glued in. Thus, the #8 trim head deck screws are ideal for use with the Drill & Drive Kit.
