The SEM or combi screw is a simple idea that has been around for a long time.

Combining a screw with one or more free spinning captive washers into one unit. But not everyone is aware of how much time they are able to save using this type of fastener…

Not only does a SEM fastener reduce part count and wastage (lost washers that have slipped out of hand and rolled into a dark place never to be seen again…). But it also benefits the user with time saved on applications when using it. With the operator only needing to fasten exactly what they need to, efficiencies are gained without having to fumble with one, or a collection of washers onto a thread whilst applying tightening torque. The simplicity of having the washers attached to an all-in-one encapsulated unit simplifies the task to speed up production and minimise errors in application.

At Staytite we stock many different types of SEM to suit a wide range of applications available for next day delivery.
