Screw caps for nuts and bolts.
The self-cutting threads created during installation guarantees a firm and secure hold.
The advantage of this type is the screw-in self-cutting fit. Thanks to its threads ridges, it works independently of the screw thread.
The entire screw connection is protected, from washer to nut and screw projection.
This screw cap is also available with an additional TPE-Seal. See EBM.
