Summary: After using hand tools for a long time, I had my doubts that this "universal" socket could work; However, I was visiting a friend and had a chance to tinker with one and they seem to work, especially for unusual shapes. 4 inches, and the larger (this one) is 32 mm (1-1/4 inches). This versatile head is great for custom shapes and low torque applications. It's also handy to have an outlet that works with both metric and standard. That being said, there are some applications where this should not be used; The most common are high torque applications. For example, my motorcycle's rear axle nut is 30mm in diameter and although this nut will grip the nut, high torque (+80 ft-lbs) can cause the nut to slip which can damage either the nut or the nut ( or both). ). in progress; It is best to use the correct size socket in this application. Pros: good fit and finish; smooth operation; Includes 1/2" drive to 1/4" hex adapter. Cons: Cost (higher than similar offerings). Conclusion: 4 stars for $24, mainly because of the price.
