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.

Key Features

• Heavy-Duty 8.0mm Go-Through Shank: Solid one-piece steel construction withstands hammer blows to loosen stubborn screws.
• Thick Hexagonal Shank Bolster: 8.0mm hex profile accepts wrenches or spanners for high mechanical turning leverage.
• Broad 8.0mm Slotted Tip: Engineered for heavy industrial flathead screws, delivering deep slot engagement.
• Industrial CR-V Steel Construction: High-impact Chrome Vanadium alloy resists fracturing and tip deformation.
• Ergonomic Shock-Dampening Handle: Molded two-color grip absorbs impact recoil while preventing hand slippage.
• Display Hanger Included: Supplied with a dedicated plastic hanging fixture for wall racks and pegboard setups.

Applications

• Breaking loose heavily rusted, painted, or seized large slotted screws on industrial machinery
• Commercial truck and trailer maintenance, heavy vehicle axle and brake assemblies
• Heavy plant maintenance, pump casings, and large motor disassembly
• Structural mechanical maintenance where extreme turning leverage and hammer strikes are required
