Abstract
A telescoping fastener includes a debris clearance and drain port in a housing of the fastener, and a plunger operable in the housing to move contaminants toward the port for removal. A force concentrating tip breaks up snow, ice or accumulated debris. Relief channels in the plunger facilitate movement of contaminants around the plunger and movement of the plunger through contaminants within the housing.
