The DongCheng HD090900 6 x 100mm Go-Through Slotted Screwdriver is engineered to loosen seized, rusted, and overtightened slotted screws. Built with a solid go-through steel core extending from the 6.0mm flathead tip entirely through the handle to a hardened steel striking cap, it allows hammer blows to break stubborn fasteners without fracturing the handle.

Forged from premium Chrome Vanadium (CR-V) steel, it features a 6.0mm hex shank that accommodates a wrench or spanner for additional rotational torque. The ergonomic two-color handle absorbs striking shock and provides non-slip hand comfort. Supplied with an individual plastic hanger for wall rack and pegboard organization.

Key Features

• Go-Through Steel Core with Striking End: Solid internal steel bar transmits hammer strikes directly to the screw head to shatter rust and corrosion.
• Hexagonal Shank Bolster: 6.0mm hex shank allows wrench or spanner engagement for extra rotational leverage.
• Chrome Vanadium (CR-V) Steel: Hardened alloy steel construction prevents tip chipping and shank twisting.
• Precision 6.0mm Slotted Tip: Flathead profile seats snugly in fastener slots to minimize slippage.
• Shock-Dampening Ergonomic Handle: Contoured grip absorbs hammer impact recoil while providing slip resistance.
• Plastic Hanger Included: Supplied with a dedicated hanging bracket for organized shop storage.
