Vilken skruv? — a Swedish screw-and-wall decision tool

Field notes

The main selector uses substrate, mounted object, risk level, environment, and available reinforcement to narrow the user toward a fastening family. It covers gypsum board, concrete, wood, brick, lightweight concrete, and thin metal, while separate selectors address plugs, drills, screw length, and wall-material identification. The page explicitly withholds invented load figures and directs users to manufacturer documentation for exact dimensions and allowable loads, especially for safety-critical installations.
