Three-Drive U-Joint Set
This Powerbuilt 640858 set supplies three universal joints in 1/4", 3/8" and 1/2" drive sizes. Mechanics and DIYers can reach fasteners at awkward angles without binding the ratchet. Each joint is built for standard hand-tool torque in automotive and general maintenance work.
Replaces Single-Drive Joints
Instead of buying separate joints for each drive size, this kit covers the three most common ratchets in one purchase. The upgrade is worthwhile when you regularly switch between 1/4", 3/8" and 1/2" tools and want a matched set that stores together. Buyers who need only one drive size or who require impact-rated joints should look elsewhere.
Check Drive Compatibility
Verify that your existing ratchets and sockets match the three drive sizes listed. Confirm the joint pin diameter suits your socket retention method. Note the California Proposition 65 warning: the product contains a chemical known to the state to cause cancer and reproductive harm. Orders of $75 or more ship free from the manufacturer.
