Take it easy tool finder-Color coding system for quick and easy tool size selection;unique rubber holder design to access to individual sizes without needing to rotate above sizes allen wrenches. Comfortable grip-Allen wrenches made from round material are more robust,particularly where smaller sizes are concerned; Shrinked with environmentally friendly EVA sleeves,providing a pleasant grip,especially in applications at low temperatures. Extra long length to fit perfectly in the hand-People who tighten a lot of screws need a tool that sits perfectly in their hands. We have therefore extended the allen wrenches' handle lengths in comparison to the ASME standard in order to provide better ergonomics. This gives users better access and allows them to work more precisely. No more dropped screws-Patented magic magnetic system for magnetizing to achieve screw holding function,which is especially helpful in confined,hard to reach spaces,where there is no room for a second hand to secure the screw on the tool.Demagnetizing to avoid iron filings. High Torsion Strength and machining accuracy-The biggest factors that determine the quality of Allen wrenches are torsional strength and processing accuracy. In order to achieve torsional strength that will not break even when strong torque is applied, steel needs to find the optimal balance of hardness and toughness. The steel we use is special alloy steel CRV specially developed for hexagon wrenches, developed jointly with steel manufacturers in order to pursue an ideal balance ratio.HRC from, Weight: 1.65 pounds, Manufacturer: Kraftek
