Meaning
Norwegian
has gloss	nor: En blindmutter er en sylindring, internt gjenget nagle som kan trekkes mens man jobber fra én side. Den utvides da på den blinde siden, som gjør at den sitter fast. En skrue kan da skrus i gjengene i blindmutteren, noe som gjør at man kan skru braketter, håndtak og lignende på flater man ikke har tilgang til baksiden av.
