The Stanley-Proto POJ61390 91-piece multi-bit kit comes with two drivers and features a high-polish, mirror-finish center shaft that eliminates the need for a socket wrench on many fasteners. The included 3/8-drive torque adapter has a 1/4-inch shank measuring 13/16 inch, with a torque limit indicator in Newton Meters (Nm) to help prevent over-tightening and damage to fasteners.
This kit serves as a direct replacement for the discontinued 91644A and 91645A Torque Adapters, making it an ideal upgrade or replacement solution for professional tradespeople and MRO applications. The comprehensive 91-piece assortment provides versatile bit coverage for a wide range of fastening tasks in industrial and maintenance environments.
