SEMS SCREWS

SEMS Screws are screws preassembled with free spinning washers. The   assembly typically contains one plain washer and one split spring washer. The washers are held in place with the major diameter of the thread being larger than the hole of the washer. This is achieved by inserting the washers before thread rolling.
Advantages
– Increased productivity by eliminating hand assembly of washers with the screws.
– Permanent assembly ensuring that the washers are not misplaced.
– Safety for the product as there is no chance of a washer being dropped into the assembly.
