Which of the following is NOT a recommended practice when installing deadbolts?

Choosing a 3/4 inch screw is not considered a recommended practice when installing deadbolts. Deadbolt security hinges on the strength and durability of the components used, and the length of the screws plays a critical role in this. A 1 inch screw is preferred because it provides more anchoring strength by extending deeper into the door frame, securing the deadbolt better against forced entry attempts.

Using a 3/4 inch screw could leave the deadbolt frame less secure, as it may not penetrate the door frame sufficiently, making it easier for a potential intruder to bypass the lock. In contrast, the use of a solid strike plate and a durable lock brand enhances security; the strike plate reinforces the area where the deadbolt engages, and a reliable lock brand ensures better quality and resistance to tampering. Thus, opting for the recommended inch screw ensures the integrity of the deadbolt installation.
