What size drill bit is recommended for installing a 1/4-inch concrete screw?

To install a 1/4-inch concrete screw, a 3/16-inch drill bit is recommended for the pilot hole. This is correct because concrete screws require a pilot hole that is slightly smaller than the diameter of the screw itself. The smaller pilot hole allows the threads of the screw to engage the concrete effectively while minimizing the risk of cracking or damaging the surrounding material.

Using a drill bit that is too large can result in insufficient grip for the screw, leading to a weak installation. Conversely, if a drill bit that is too small is used, it may be difficult to insert the screw and could cause damage to both the screw and the surrounding concrete. That’s why the 3/16-inch drill bit is the appropriate choice for a 1/4-inch concrete screw installation.
