ABSTRACT:
A panel fastener having a turning knob which is attached to a stud in a positive locking relationship. The stud has a shaft with an enlarged stud head and a deformable lip at one end and a threaded region at the opposite end. The hollow cylindrical knob has an interior annular ridge extending radially inwardly from the inside surface of the knob thereby defining an opening through the knob. The stud extends through the ridge opening and the stud head rests on one surface of the ridge and the lip extends from the stud head through the ridge opening and is deformed to engage the ridge to permanently attach the knob to the stud. The stud head has protrusions extending radially from its circumference which positively engage a similarly shaped recess in the knob. The knob is made of a composite material that resists cracking during assembly and reduces corrosion during use.
