Will these work on interior trim clips and electronics?

Yes. T-handles give you the control needed for small fasteners without over-torquing. They're ideal for dash panels, door cards, and under-dash connectors where precision matters.

What sizes are included?

You get a full range of Phillips and slotted head sizes in one set. The variety covers most interior and light mechanical fastener work.

Are these better than a power screwdriver for delicate work?

For sensitive jobs—trim clips, electronics, anything that can strip or break—hand tools give you the feel and control a drill can't match. The T-handle grip makes that control easier to sustain.
