ABSTRACT:
A plastic nut comprises a cylindrical body incorporating in the tubular wall thereof resilient pieces provided on the inner surfaces thereof with check screw threads. When an ordinary bolt is simply pushed in the nut, the check screw threads of the nut engage themselves inseparably with the screw threads on the bolt. The union thus formed is retained strongly and lastingly. Dissolution of this union is obtained by rotating the nut around the bolt.
