Prabhat tool industries offers hex [allen] drivers, made out of high-grade 52-alloy steel. These hex drivers are hardened as per international specification to achieve a good torsional strength at a high hardness of 5960 hrc. This good hardness and toughness combination gives a very long life to the driver tool compared to the conventional hex drivers available. Each hex driver is duly faced and chamfered for easy working and better aesthetics. The company uses the latest finishing technology to achieve mirror-like finish on the tool surface and proper coating [black-oxide/nickel chrome] is done for good looks and prevention from rust and oxidation. All the drivers are kept in proper holders/jackets to prevent the tool from getting misplaced and provide convenience in storing. Hblk-l00 [9-pieces ball type long series allen keys set]: unique ball design for operation with key tilted up to an angle of 30° [sizes 1.5,2,2.5,3,4,5,6, 8 and 10 mm]. This reduces the allen bolt running time by 100%, saves precious man-hours and increases productivity. The extra-long keys allow greater leverage in operation, thereby reducing operator efforts.
