Explosion opening width adjustable wrench can be used to dismantle the hex head or square head bolts and nuts. Manufacturing Process: Forging Material: Aluminum bronze beryllium my company's proof tool is the result of a large friction presses rolling 300-2500T from its mechanical properties, torsion, tension-proof Swedish S-tube clamp strength, more than the technical level of the world's countries. Our products are mainly divided into two categories: Explosion tools: aluminum bronze, beryllium copper. Nickel aluminum, nickel beryllium alloy smelting. Beryllium is a national tool ⅡC level products, operating at 21 percent concentration of hydrogen not detonate gas; ⅡC aluminum bronze tools is a national-level products, operating at 21 percent concentration of hydrogen gas in the gas does not detonate. Beryllium is zero because the magnetic material, so beryllium tool known as magnetic tools available in the safe operation of the magnetic field environment. Explosion magnetic tools are the following categories: A: The specifications of the sleeve and Annex B: all kinds of wrenches, such as double-mei, percussion, hex, wrench C: all kinds of hammers, such as claw hammer, Sledge Hammer test hammer copper hammer, etc. D: all kinds of shovel type, down class shovel rake class E: flat shovel crowbar class F, scissors and pliers various categories such as pliers, diagonal pliers, nutcracker, water pump pliers G: screwdriver Class H : Listen needle, top class I: handsaw, Puller, chain hoists, monorail, electrostatic discharge device J: various combinations of tools
