The Lighted Cordless Precision Screwdriver (502) can help users handle difficult, repetitive fastening jobs involving tiny screws in tight spaces where it is difficult to see. For HVACR technicians, the screwdriver is an ideal tool for low-light applications, such as adjusting HVAC controller settings in thermostats, boilers, and furnaces, the company said. The pen-sized tool has a high-powered LED, which shines directly on the work area. Features include the exclusive Super-Torque drive, which generates 100-plus revolutions per minute (rpm), powered by two AAA batteries, which are included; ergonomic rubber grip; and ABS housing. The Lighted Cordless Precision Screwdriver comes complete with six interchangeable 4 mm bits — slotted: 1⁄8 and 1⁄16 inch; Phillips: #000 and #0; and Torx: T5 and T6. Its quick-change chuck enables effortless swapping between bits and, with its universal design, it can accommodate all standard-sized 4-mm technicians’ bits available on the market.
