The Vessel 910S4100 MEGADORA Thin Shank Screwdriver carries a slotted (SL4) tip on a narrow 4mm shank, built for screws in tight or delicate assemblies rather than general hand tool work.\u003c\/p\u003e\n    \u003cp\u003eVessel describes this as a \"precision type\" driver, purpose-built for 4mm or smaller blade diameters - a category apart from its Standard and Tang-Thru MEGADORA lines, which use thicker shanks meant for higher-torque driving. The tip carries a black-point finish that Vessel states holds up regardless of plating thickness on the screw itself, which matters on small plated fasteners where a driver can otherwise slip up out of the slot.\u003c\/p\u003e\n    \u003cp\u003eSpecs on this model: a 0.5mm tip thickness, 4mm shank diameter, 100mm shank length, 21mm grip diameter, and 178mm overall length.
