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-5ua9{font-weight:bold;text-align:left}.tg .tg-0lax{text-align:left;vertical-align:top} Beta Tools -Spark-Proof Screwdriver Slotted Head Range Product Code Part Number AxL L1 Weight mm mm g 12700803 1270BA 3X75 3x75 178 70 12700804 1270BA 4X100 4x100 209 50 12700805 1270BA 5X150 5x150 250 70 12700806 1270BA 6X150 6x150 270 105 12700808 1270BA 8X200 8x200 312 165 12700810 1270BA 10X250 10x250 382 240
