DongCheng 6 x 100mm Go-Through Slotted Screwdriver (HD090900)
Have a question?
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.
