A construction fastening device of the type which would engage a mating device upon application of engaging means, comprising:
- (a) a cam device, further comprising:
- i) a half-circle plate having a front and back side, said plate being rigidly mounted upon an axle;
- ii) a flange rigidly connected to and extending from both sides of said plate along the full circumference of the plate;
- iii) a magnetic slug which is rigidly attached to said plate at one end of said flange;
- (b) a first housing in which said cam device is contained, said housing having two broad sides separated by four narrower sides, one of said narrower sides being opened such that said cam device can extend therefrom when operated, each of said broad sides having a round opening centrally located such that said axle fits loosely thereinto and having a gasket fitted between said axle and opening;
- (c) means for securing said half-circle plate against said first housing when cam device and mating device are in either the engaged or disengaged position.
