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-s268{text-align:left}.tg .tg-0lax{text-align:left;vertical-align:top} Product Code Part Number Key Dimension L L1 Weight mm mm mm 000961799 96BA/BP 1.5 1.5 50 16 3 000961800 96BA/BP 2 2 50 16 3 000961801 96BA/BP 2.5 2.5 63 20 5 000961802 96BA/BP 3 3 60 20 5 000961803 96BA/BP 3.5 3.5 70 25 12 000961804 96BA/BP 4 4 66 25 12 000961805 96BA/BP 5 5 75 28 22 000961806 96BA/BP 6 6 84 32 30 000961808 96BA/BP 8 8 92 36 56 000961810 96BA/BP 10 10 102 40 100 000961812 96BA/BP 12 12 113 45 175
