Pre-drilling screw holes before installing reinforcement hardware prevents wood splitting and preserves door jamb strength.

When you pre-drill, choose a drill bit that is slightly smaller than the screw shank so the threads still bite while the core of the screw displaces less wood. For dense hardwoods pick a bit closer to the inner core diameter to reduce insertion torque and the chance of splitting. Drill to a depth that matches the screw length using a tape stop or depth collar so you avoid bottoming out or cracking through. Countersink shallow trim and reinforcement plates so heads sit flush and do not create leverage points that can lift the wood. For retrofit installations reverse the screw a quarter turn after initial insertion to compress wood fibers back into the hole then drive forward fully; this reduces play and improves holding power. Always drive final screws with an impact driver on controlled torque rather than a standard drill to seat screws rapidly without overtorquing and to minimize heat and wandering that can create microcracks.

Common mistakes include using a drill bit that is the same size as the screw which causes excessive friction and splitting; fix this by selecting a bit slightly under the screw shank diameter so threads engage but wood is not forced apart. Another issue is not drilling to the correct depth which leads to screws bottoming out and failing to draw mating surfaces together; use a depth stop or mark the bit with tape and verify depth before driving the screw. A third problem is overtightening with a standard drill which strips or crushes the wood fibers; switch to an impact driver with controlled torque and countersink heads when needed to distribute clamping forces.
