Those look like timberlok screws, so it would then have been a 5/16 hex driver. The box of screws comes with a driver bit with a 1/4" hex quick-release end which fits impact driver guns. Ledgerlock screws are 3/8"; Headlock screws are a special 11-spline driver that is proprietary; but a box in any case comes with the appropriate driver bit, and replacements are sold in the aisle with the fasteners.

Haven't seen the Vid but most purpose-built cordless impact drivers are 1/4: hex-drive. Some of these are quite strong. 3/8" and 1/2" square-drive models are also available but overkill for smaller diameter screws like Timberlocks. I've got a DeWalt DC826 on my wish-list for this week.
