Abstract: Blind hole locating systems, devices, and methods are provided. A method includes installing a guide screw into a blind hole of a first material and assembling a drill guide apparatus, which includes removably coupling a drill guide to a guide strap and inserting a guide pin through a drill guide hole of the drill guide so that a length of the guide pin protrudes past the guide strap. The method also includes placing the drill guide apparatus on the first material so that a portion of a length of the guide pin protrudes into the guide screw, securing a portion of the guide strap to the first material, and removing the guide pin while the guide strap remains secured and placing a second material over the blind hole (including the guide screw in the blind hole) and between the guide strap and the first material.
