Abstract: A fastener extractor and a method of extracting a fastener are provided. The fastener extractor includes a shaft, an engagement end at a distal end of the shaft and an attachment end at a proximal end of the shaft. The engagement end includes a plurality of helical ridges and grooves. The attachment end extends axially from the shaft and includes a hexagonal cross-sectional portion adapted to engage an extraction tool. Adjacent ones of the plurality of the grooves form the ridges therebetween and the plurality of ridges is adapted to engage a pre-formed opening in a fastener to be removed.

Abstract: A protective shelter that is made from a plurality of elongate, vertical C-shaped panels that have web portions and perpendicular side portions, and are butt connected together with fasteners that are located in a section of the side portions that are closest to the inside portion of the shelter. A connecting cap is connected around the side portions of at least some of the adjacent panels. A cap connects a roof to the upper portions of the panels and the lower part of the panels are connected with fasteners to a base that in turn is connected to a floor.
