28 precision pieces, organized in a cobalt-blue case with clear lid and four yellow trays. Short power bits, nut-driving sockets, a magnetic quick-release holder and long bits — color-ring coded so the right drive is always one glance away. Built for HVAC, electrical, appliance and mechanical work where screws and hex nuts share the same job.

Every bit carries a color ring on its base, matched to its drive family:
Size markings are laser-etched on every bit base and socket face for quick identification.
Manufactured in an ISO 9001 / 14001 / 45001 triple-certified facility. Bits and sockets are hardness-checked per lot; every set is inspected before packing.

The set ships in a rugged cobalt-blue case with a transparent lid — contents visible without opening — a folding hanging hook for wall or pegboard storage, and side slots for modular linking with other AMSUO cases. Four yellow trays hold every piece in its own slot for fast inventory, transport and retail display. Custom retail packaging and display solutions are available through our packaging program.
Common screw drives (PH, PZ, Torx, Slotted) plus SAE hex nuts from 1/4" to 7/16" — the everyday mix for HVAC, electrical, appliance and mechanical work.
The magnetic quick-release holder and sockets use the standard 1/4" hex drive, compatible with impact drivers and drill/drivers.
