                               SEMS(TAPPING) SCREW 



SEMS combines two normally seperate parts-typically a screw and a washer- into one permanently pre-assembled cost saving component. Washers are hel in place under the screw head by the rolled threads; they will not fall off and are free to rotate

Advantages:

 

* Speeds: production by eliminating hand assembly at the work station

* Permanent: Capturing of washer insures that it will never come off or be left off your assembly

* Adapts easily to automated feeding devices and driving tools

* Available in any combination of screw type, head style, washer and thread configuration

* Production Range: M2.5 (#2) ~ M 12 ~ (1/2". Length: 4mm (5/32") ~ 160mm (6")

* ISO 9001 certificated manufacturer & exporter
