Capri Tools CP31210-M13O 13 mm Open End Torque Wrench Head

13 mm open-end torque head

The Capri Tools CP31210-M13O is a 13 mm open-end interchangeable torque wrench head built for technicians who need a precise fit on metric fasteners. It is made from heavy-duty steel with a premium matte finish for durability in professional workshop environments. This head is designed for use with Capri Tools interchangeable torque wrenches and other brands that accept the same drive cavity.

14 mm x 18 mm drive cavity

The single specification that decides compatibility is the 14 mm x 18 mm drive cavity. Only wrenches with this exact rectangular opening will accept the head securely. Buyers whose torque wrenches use a different cavity size or a round drive cannot use this head and must select a different model.

Sustained workshop use

Under repeated tightening cycles the heavy-duty steel construction resists rounding and maintains dimensional accuracy on the 13 mm opening. The matte finish reduces glare and resists corrosion during long service intervals. California Proposition 65 notices apply because the product contains chemicals known to the state to cause cancer and reproductive harm.
