Abstract: An adaptor for a fastener driver assembly employs a bi-positionable angle guide assembly mounted to a head having an entry reference surface defining an opening for a fastener. The adaptor provides a proper location and entry angle for the fastener for implementing various structural connections. A pivotal angle guide has a pair of reference engagement edges functionally configured to engage either an upper horizontal member or a lower horizontal member. A locator having a location reference is mounted to the guide assembly. In one mode, the reference edges, together with the location reference, define a proper entry location and normal angle for connecting a horizontal member, which may be either an upper plate or a lower plate, to a rim board or other structural member. The selected adaptor position is achieved by securing the adaptor in one of two stable angular positions relative to the drive axis of the fastener driver assembly.

Abstract: A heat generating structure includes a substrate, a coating and a polymeric material. The substrate comprises a first material. The coating comprises a second material, different from the first material that covers at least a portion of the substrate. The coating and substrate, upon being thermally energized to their minimum alloying temperature, react in a first exothermic reaction that is an alloying reaction. The relative quantities of the substrate and coating are such that the first exothermic reaction yields a first amount of exothermic energy that is insufficient to cause self-sustained propagation of the first exothermic reaction. The polymeric material covers substantially all of the substrate and coating, and is different from the first and second materials. The polymeric layer, upon being thermally energized, reacts with at least one of the substrate and coating in a second exothermic reaction.
