The DongCheng HD090903 8 x 200mm Go-Through Slotted Screwdriver is built for heavy-duty industrial disassembly, stubborn mechanical fasteners, and high-impact extraction of rusted or frozen flathead screws. Featuring a thick 8.0mm hex shank forged from premium Chrome Vanadium (CR-V) alloy steel, the solid steel core runs directly through the handle to an integrated metal striking cap.
This through-tang design allows direct hammer strikes to crack loose stubborn corrosion and paint, while the hexagonal shank allows wrench or spanner assistance to apply maximum breakaway torque. The precision-machined 8.0mm slotted flathead tip provides solid slot seating to eliminate cam-out and head stripping. Fitted with an ergonomic two-color soft handle, it absorbs impact vibration and delivers non-slip grip control. Includes an individual plastic display hanger for convenient workshop organization.
