Impact-grade adapter set

The Baldwin AUS001-9017 set contains three socket adapters measuring 3 inches long with a 1/4 inch hex shank. It converts any power drill into a power nut driver and covers 1/4 inch, 3/8 inch, and 1/2 inch drive sizes. The adapters are rated for a maximum torque of 72 N·m and work with all brands of electric drills and screwdriver handles. Buyers who need longer extensions or non-impact sockets will not find them here.

Heat-treated chrome vanadium steel

Each adapter is made from heat-treated chrome vanadium steel with a manganese phosphate coating for rust and corrosion resistance. The finish meets and exceeds ANSI/ASME standards updated in 2024. Chamfered edges and a spring-loaded detent ball lock securely into the driver head to prevent slipping under high torque and vibration. Builders who require stainless steel or a different coating specification are not served by this set.

Organiser holder included

The 12-pack box includes a handy organiser that keeps the three adapters together and easy to locate. This solves the problem of misplaced adapters when switching between drive sizes at home, in workshops, factories, or on construction sites. The holder works with all quick-change systems and standard drill chucks for fast swaps. Users who prefer magnetic trays or wall-mounted storage will not get those options in this package.
