Although there are screws that are much better at this than others you're using 2x material which is inherently a bit weak, so dowels would be the far superior choice. Screws on the other hand can be used in pocket holes, which can speed and simplify the whole construction process. | |

If it’s going to be a static framework to support something then a screwed butt joint may be enough but if it’s any kind of moving object (you say “the moving frame”), be aware that screwed butt joints tend to loosen over time when moved. Also even if the frame is stationary then it depends on how it will be loaded. It seems this might be a case of an XY problem: perlmonks.org/index.pl?node_id=542341 - you're asking about what you think the solution might be rather than directly asking about the problem | |

I suspect the strength difference will be related to the clamping force of the screws (with glue) compared to the clamping force applied to the doweled parts (with glue). A weak clamp on the doweled parts means weak joint. A loose screw means weak joint. | |
