Why is there a StarDrive in Synthes Locking Screws?
The StarDrive recess in the head of the locking screws can withstand 65% more insertion torque than conventional hexagonal screws. The StarDrive Screwdriver is also self-retaining, so there is no longer a need for a holding sleeve. It is important to note that use of the appropriate Torque Limiting Attachment (TLA) is recommended when inserting locking screws under power to reduce the risk of applying too much torque and causing cold-welding of the screw head in the plate.
