Spingler screws can be easily distinguished from other screw types. The characteristic feature of the tinglers screw is a large sealing washer which is mounted directly under the screw head. This sealing ring makes the stainless steel screw not only weatherproof, but also waterproof.
spingler screws are screwed directly through the component to be fastened into wood or masonry and protect the underlying components from moisture and resulting structural damage. (Attention: On solid substrates, such as masonry, a dowel must of course be inserted into the wall beforehand.)
Application examples can be found indoors and outdoors, such as in roof construction, chimney construction or for the installation of skylight domes. Especially where moisture should not penetrate, tinsmith screws are the right choice.
