164A Non Sparking Ring Wrench for Extension Bar
The 164A non sparking ring wrench is usually used with the extension bar that helps the wrench to reach bolts otherwise unreachable with a standard wrench. Thanks to the bar, the wrench can turn the deeply-recessed bolts easily and with little effort. Its box end and handle are joined together via a dowel pin, which facilitates wrench assembly and disassembly.
The wrench is made strictly according to the Q/ZBF-164A standard. It is drop forged from copper alloy, which provides the wrench with various desirable features such as high tensile strength, spark resistance, long service life, and stable mechanical properties. Commonly used in the flammable or explosive atmosphere, the wrench is mainly employed to remove or fasten large hex-head bolts and nuts.
