Hex Bit Adapter Bushings for Sockets and Box-End Wrenches (SCAD)

These are bitholder bushings for use with sockets, box-end wrenches, and ratchet wrenches. Primarily, this is useful where you need to use a standard insert bit, but you have no height clearance or need a bit more torque or right-angle access. They aren't particularly strong, but they're strong enough to sink deck screws into yellow pine -- even with an impact wrench. While they can withstand a lot of torque compared to typical grip torque on a screwdriver, a wrench can easily provide an excess of torque beyond that. Expect that you can break one or at least eventually wear it out. Considering that they cost about $0.01-0.03 to print, this is acceptable. There is an option for a 6pt model, but it may be notably weaker if used in a 12pt or open-end wrench. It's intended strictly for use in a 6pt socket or box-end. I have not tried either in a flank-drive type wrench, but i expect that it may also underperform, as it allows more room for the displacement of plastic. Clearances
