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.Compact heads | High resistance to corrosion | Avoids improper rust formation | Outstanding mechanical characteristics | Compact support | Handy & easy to carry | Quickly identify each spanner | Lock safely into the compact supportContents: 6 - 8 - 10 - 11 - 12 - 13 - 14 - 15 - 16 - 17 - 19 mm
