I've used the Kreg jigs for years, including the longer screws if assembling 2x material. While strong, those connections were not in the same league as framing connectors or a proper nailing schedule. These new HD screws are a substantial step up, and make a connection in 2x, especially at corners, that exceeds nails or even most screws. I'd compare it more to lags bolts or screw-fastened connectors. In fact, it is strong enough that slight issues with saws will become noticeable. My practice project with these was a window seat with storage, and the screws kept pulling the frame a bit out of square. Damned if my miter saw wasn't a degree or so out of true. You may find that waiting to fully tighten these screws until most of a frame is assembled keeps you from mumbling as many invocations. As with the smaller screws, keep in mind that the process does not provide for starter holes in the second piece of material, so if you fasten very close to an edge and experience splitting you'll need to consider making those holes. Fastening the screws part-way will mark that process nicely. The jig works almost just like the original (and the mini), and fits in the stand or on the clamp frame. The difference is it lacks an adjustment for material thickness: this is set for 2x boards. I've yet to try it, but it would likely work fine drilling into a 4x4 or larger post.
