Description The most common wrench is a design that combines an open-end and a box-end profile. The combination of the two single-size profiles compensates for the shortcomings of each individually. The "W264" series of combination wrenches have inch-sized working profiles. The products are made of chrome-vanadium steel according to the ANSI/ASME B107.6 standard, comply with GOST 2838-80, are mirror-polished, and have a triple-layer chrome-nickel coating. Upon customer request, combination wrenches of the "W264" series can be supplied up to 2-3/4" in size. Technical specifications Length, mm 161 Min size 3/8" Max size 3/8"
