<!382>4.0mm Locking Self-Tapping Cortical Screws

Description
The 4.0 mm Universal Locking, Self Tapping Cortex Screw is designed to fit the VID Universal Locking Plates. Pre-drill with a 3.2 mm drill bit. No tapping necessary. The screw can be inserted into any 2.7 mm or 3.5-4.0mm VID Universal Locking plates equipped with a 4 notch locking hole. The VID 4.0 mm drill guide must be used for proper hole positioning. The screw can be inserted perpendicularly to the plate with the straight drill guide or can be inserted with a 15 degree variation in 360 degree direction to a total of 30 degree angle using the funnel end of the drill guide. The screw can be inserted and removed several times in the straight in configuration and can be inserted or removed a few times in the polyaxial configuration before it would fail to lock in.

Additional Notes & Tips
This screw is equipped with a standard AO/ASIF hex head accepting the same standard 2.5mm AO/ASIF hex screw driver used for 4.0 mm AO/ASIF screws. The screwdriver fits into the head deeper than with an AO/ASIF screw for additional torque power. There is no need for torx screw driver. The design is sufficient to lock in with applying regular force.
