The Beta INOX range of stainless steel tools can be used in critical environments where contamination is not permitted. All Beta INOX tools can be autoclave sterilized at 121˚C.These tools avoid improper rust formation. Whenever any tools other than those made of stainless steel are used on stainless steel screws, nuts or other surfaces, a few particles may come of the tool, thereby triggering corrosion.Accurate selection of material and the expert quest for the best heat treatment provide the Beta INOX tools with mechanical characteristics which far exceed the statements and are comparable to those of the other Beta Tools. The INOX range share the same ergonomic properties and design as the other Beta Tools, which have been known to, appreciated by, professional users for over 75 years.The INOX range uses magnetic stainless steel AISI 420.Ball head offset hexagon key wrenches, made of stainless steelHigh resistance to corrosionOutstanding mechanical characteristicsAvoids improper rustBall head makes it possible to work at angle of up to 30° to screw axisFor tightening use short side, if possibleAISI 420 stainless steelSizes: ​5/64 | 3/32 | 1/8 | 5/32 | 3/16 | 7/32 | 1/4 | 5/16\"
