ABSTRACT:
A device for coating the internal threads of a fastener includes a rotatable base for holding the fastener, and an applicator having a discharge orifice extending through its side wall which contacts the internal threads at a single point of tangency, the axis of the applicator being offset from the rotational axis of the base. Thus, an induced side load force is created at the point of tangency for effecting the pressing of discharged sealant into the roots of the threads. Differently sized internally threaded elements can be coated in accordance with the invention while using the same sealant applicator.
