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.

Key Features

• Full-Length Go-Through Core: Solid steel shaft transmits hammer blows directly through the striking end cap to the fastener without cracking the handle.
• Hexagonal Shank Bolster: 8.0mm hex profile accommodates a wrench or spanner for extra rotational mechanical advantage.
• Industrial CR-V Steel Construction: High-tensile Chrome Vanadium alloy resists shock impact, tip fracture, and shank twisting.
• Extended 200mm Reach: Provides access to deep-seated fasteners inside heavy industrial machinery and engine blocks.
• Broad 8.0mm Slotted Tip: Engineered for heavy mechanical flathead screws with deep slot engagement.
• Ergonomic Shock-Absorbing Handle: Contoured dual-material grip dampens strike rebound while preventing palm fatigue.

Applications

• Dislodging seized, rusted, or paint-covered slotted screws in industrial machinery and automotive assemblies
• Commercial vehicle servicing, truck brake assemblies, and suspension bracket maintenance
• Heavy plant maintenance, pump casing servicing, and electric motor overhauls
• Mechanical prying, alignment, and chisel-like striking tasks in tough workshop environments
