The present document describes a fastening strip for fastening a plurality of siding panels to a surface. The cobalt-nickel alloy cemented carbide substrate provides both erosion resistance and corrosion resistance to the cemented carbide substrate. At the same time, the epitaxially grown metal silicide can withstand a second high-temperature annealing used for improving the performance of a high-k gate dielectric material, which further improves the performance of the device. Hybrid maize seed, plant or plant part produced by crossing the variety PH1DB2 or a locus conversion of PH1DB2 with another maize variety. In one embodiment, the base includes counterbores that reduce the heat conduction path between the filament posts and the base, and moves the contact area further from the filament.
