Beta Tools Copper-Berillium (Cu-Be) Spark-Proof Tools are specifically designed for safe operations in environments subject to potential risk of explosion, in the presence of flammable liquids and gases, or for any applications that require using perfectly antimagnetic, corrosion-resistant tools.All tools are certified by the Federal Institute for Materials Research and Testing (BAM) under European Directive 99/92/EC.Warning! Risk of explosion in ACETYLENE environment. The mechanical characteristics of spark-proof tools differ from those of normal steel tools. They should be used with extreme caution, avoiding overloads..tg {border-collapse:collapse;border-spacing:0;}.tg td{font-family:Arial, sans-serif;font-size:14px;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:black;}.tg th{font-family:Arial, sans-serif;font-size:14px;font-weight:normal;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:black;}.tg .tg-5ua9{font-weight:bold;text-align:left}.tg .tg-s268{text-align:left} Beta Tools - Spark-Proof Offset Hexagon Key Wrench Range Product Code Part Number mm L L1 Weight mm mm g 000960760 96BA 1,5 1.5 50 17 2 000960762 96BA 2 2 50 16 5 000960761 96BA 2,5 2.5 56 20 4 000960763 96BA 3 3 63 21 8 000960764 96BA 4 4 69 25 14 000960765 96BA 5 5 78 29 21 000960766 96BA 6 6 88 33 33 000960767 96BA 7 7 93 34 47 000960768 96BA 8 8 97 36 65 000960769 96BA 9 9 104 37 85 000960770 96BA 10 10 110 39 110 000960772 96BA 12 12 122 44 175
