Why threaded screw plugs?

The difference between the INOSOL screw plugs and the usual expander sealing plugs is that no special tools are required for assembly and the hole is not irrevocably sealed.

Likewise, when using the threaded sealing plugs in the event of a leak, you are not faced with an “unsolvable” problem.

Furthermore, the counter material is not stressed. With the small thread sizes, the Inosol screws have a unique selling point.
