The DongCheng HD090317 SL8 x 300mm Slotted Screwdriver is built for maximum reach and high torque in deep mechanical housings, severe-duty industrial maintenance, and hard-to-access machinery panels. Constructed with an extra-long 300mm round shank forged from industrial-grade Chrome Vanadium (CR-V) steel with an 8.0mm diameter, it delivers exceptional resistance to torsional twisting and bending across its extended span.

The precision 8.0mm slotted flathead tip provides deep, snug seating in heavy screw slots to eliminate slipping. Fitted with strong magnetic retention, it securely holds heavy screws for single-handed positioning in deep blind enclosures. Its ergonomic dual-color soft-grip handle provides firm grip traction and maximum manual turning leverage. Packaged with an individual plastic hanger for convenient pegboard mounting.
