Studs, tracks and metal members used in steel frame panel systems are joined or attached to each other. Metal members (1, 2) are joined to each other by the use of depending collars (3, 4) and through holes. A tool head (11) inserted through the collars and holes and the tool shoulder (12) exert pressure to simultaneously bend and crimp the collar. This technique can also be applied to truss members or to tracks and studs so that the members are easily joined or attached to each other. Beveled ends facilitate the alignment of collars with the holes. |
