The DongCheng HD090902 8 x 150mm Go-Through Slotted Screwdriver is built for heavy-duty industrial disassembly, stubborn machinery fasteners, and high-impact bolt and screw extraction. Built with an extra-thick 8.0mm hex shank forged from industrial-grade Chrome Vanadium (CR-V) steel, the full-length steel rod runs directly through the handle to a wide steel striking cap.
This design allows direct hammer blows to loosen frozen fasteners while allowing a wrench or spanner to be applied directly to the hex shank for extra torque. The precision-machined 8.0mm slotted flathead tip provides deep, non-slip slot engagement to prevent head stripping. Its ergonomic dual-color handle delivers shock absorption and secure grip control. Packaged with an individual plastic hanger for pegboard mounting.
