The screw is used with compatible locking plates to provide stable fixation of bone fragments. When locked into a compatible plate, the screw head forms a fixed angle construct that can contribute to construct stability.

Self drilling means the screw is designed with a tip that can facilitate penetration into bone, while self tapping refers to the screw's ability to create or form its thread path as it advances. The specific surgical technique should follow the applicable system instructions.

No. Compatibility depends on the plate design, screw thread specifications, diameter, and locking mechanism. Surgeons and medical professionals should use the screw only with compatible fixation systems and according to the manufacturer's instructions.

Locking screws can provide angular stability when properly engaged with a compatible locking plate. This may help maintain the intended fixation construct, particularly when conventional screw purchase or compression is not the primary fixation strategy.
