The Pro Cassette Lockring Socket begins as a solid piece of alloy tool steel, then is fully machined to precise tolerances for an exacting fit you won’t find anywhere else, and finally is optimally heat treated for maximum strength and longevity. Designed with the professional mechanic in mind, the extra-deep splines ensure superior engagement while the quick spin knurling provides speed and control. Use on your Grande Torque Wrench for proper torque or use with our Pro Socket Handle or Equalizer Pedal Wrench to remove that stubborn lockring requiring a little extra leverage. Backed by Pedro’s lifetime warranty.
