Production of small stamping parts and turning parts.

Everyone knows the problem of corrosion, it is shown to cause damage amounting to about 3% of the annual gross national product. Particularly common is the corrosion of threaded fasteners.

The screw is probably among the most important inventions of mankind. To protect you, is a real challenge.

Bolted connections are found in all areas of daily life. As long as they work, we're not thinking about them. Must rusted screws on supply systems or other vital parts solved but, most of the trouble starts. In time-consuming and cost-intensive work, they are solved, sawed or drilled out and must then be replaced.

Even the well-intentioned protective coating does not solve the problems. At the latest after the second coat of paint, the threads are added and a release is impossible. A coat of paint can not protect against aggressive media, because the coatings are designed in most cases for such loads, and often do not reach the threaded base.

Remedy can only offer bolted from high quality stainless steel screws or caps here. Since stainless bolts and nuts are very expensive and can not be used anywhere (risk of electrolytic corrosion when connecting materials of different weights!), Screw caps are in most cases the cheaper solution. They protect the important screw from corrosion and environmental influences. Thereby increasing the life of the glands and thus reduce the cost of maintenance.

Screws, nuts and accessories are largely internationally standardized, the resulting compounds are designed screws but as diverse as the art itself, and experience has shown to not alone be protected by a single "universal" cap shape.

The company RADOLID Thiel GmbH offers here different systems and a broad program to address these problems.

RADOLID caps have a round cross section, a clamping edge, thread ridges or wedges, a sealing lip and a groove.Only a combination of these essential RADOLID features together form the prerequisite for optimal function. Since there are these caps not only in different sealing lip designs, but also in various heights, this cap system has grown almost all claims.
