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 3/4\" Drive Bi-Hex Socket Range Product Code Part Number Socket Head Size Ø L L1 Ø1 Weight mm mm mm mm mm g 009260824 926BA 24 24 40 55 27 40 307 009260826 926BA 26 26 40 55 27 40 307 009260827 926BA 27 27 40 55 27 40 312 009260828 926BA 28 28 41 55 28 40.5 339 009260830 926BA 30 30 43 60 30 43 410 009260832 926BA 32 32 45 60 30 45 465 009260834 926BA 34 34 48 60 30 45 480 009260836 926BA 36 36 50 60 30 45.1 510 009260838 926BA 38 38 53 60 30 46 555 009260841 926BA 41 41 57 65 32 48 660 009260846 926BA 46 46 63 65 32 49 830 009260850 926BA 50 50 68 70 35 52 945
