Polygon Key 30X32mm with 70° angle which offers better fit for flush-mounted screws. The closed corner design provides a better grip and reduces the screw's turning. The sleek head design allows access to narrow spaces where a ratchet won't fit. The sealed high-visibility markings allow quick size identification. It features a fully polished chrome finish that wipes easily and resists corrosion. Made from chrome-vanadium alloy steel (Cr-V) for exceptional strength and durability. Conforms to or exceeds the ASME B107.100 standard.
