What does SEM mean?
In this case, SEM is simply a shorthand way of saying 'pre-assembled.'
What is the advantage of a Pozidriv screw?
A Pozidriv screw is an improvement on the crosshead screw, or Phillips screw. Like the crosshead, the Pozidriv screw naturally centers the torque when a Pozidrive screwdriver is applied, meaning there is less resistance and more control when screwing and unscrewing. To lessen the chance of the driver slipping from the screw head, known as cam out, the Pozidriv screw is preferable even to the Phillips screw.
