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} Product Code Part Number Size A Ø L S1 S2 Weight \" mm mm mm mm mm g 000420946 42BA-AS 9/32 9/32x9/32 17 14.5 120 5 7 37 000420947 42BA-AS 5/16 5/16x5/16 17 14.5 120 5 7 37 000420948 42BA-AS 11/32 11/32x11/32 22 18 135 5.4 8 55 000420950 42BA-AS 3/8 3/8x3/8 23 16.5 128 6.5 8 44 000420951 42BA-AS 7/16 7/16x7/16 26.5 19.5 135 7 9 57 000420949 42BA-AS 15/32 15/32x15/32 26 20 140 6 9 75 000420953 42BA-AS 1/2 1/2x1/2 30 21 140 7.5 9.5 74 000420954 42BA-AS 9/16 9/16x9/16 32 23.5 163 7.5 10.5 100 000420956 42BA-AS 5/8 5/8x5/8 36 26.5 177 8 12 123 000420957 42BA-AS 11/16 11/16x11/16 38 28 195 9 12.5 153 000420959 42BA-AS 3/4 3/4x3/4 42 30 215 8.5 10.5 190 000420961 42BA-AS 13/16 13/16x13/16 45 33 230 9 14 210 000420962 42BA-AS 7/8 7/8x7/8 50 38 235 10 14 250 000420964 42BA-AS 15/16 15/16x15/16 49.5 38 256 10 15.5 290 000420965 42BA-AS 1 1x1 52 39 266 11 15.5 310 000420967 42BA-AS 1.1/16 1.1/16x1.1/16 57 43.5 283 12 18 410 000420969 42BA-AS 1.1/8 1.1/8x1.1/8 61 43.5 297 12 18 460 000420970 42BA-AS 1.3/16 1.3/16x1.3/16 62 47.5 308 13.5 20 560 000420973 42BA-AS 1.1/4 1.1/4x1.1/4 66.5 50.5 324 13.5 22.5 700
