Used wherever conventional screw fasteners are needed, SEMS screws are ideal for optimized work environments due to being a pre-assembled washer and screw combination. They are designed with convenience in mind, saving you time and effort in installation. They might commonly be used in;

• Production environments
• Maintenance
• DIY Applications

In this case, SEM is simply a shorthand way of saying 'pre-assembled.'

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.
