Universal Impact Socket for Power Tools
The Capri Tools 5-3312 is a 12 mm socket with a 3/8 inch drive built for impact wrenches. Its universal joint rotates 360 degrees to reach fasteners at difficult angles. Chrome Molybdenum steel and a proprietary heat treatment handle high torque from power tools. A manganese phosphate coating provides corrosion resistance superior to black oxide.
Limits of the Universal Joint Design
The 360-degree swivel adds length and a pivot point that reduces the maximum torque you can apply compared with a fixed socket. Access improves in tight spaces, but the joint can bind at extreme angles under heavy load. The 6-point WaveDrive profile grips fastener flats to reduce rounding, yet it still requires the fastener to be in reasonable condition. ASME B107.110 compliance confirms dimensional accuracy for standard fasteners.
12 mm Size Decides Fit
This socket fits only 12 mm metric fasteners; it will not work on SAE sizes or other metric diameters. The 3/8 inch square drive matches common impact guns and ratchets of that drive size. Buyers needing a different metric size or a larger drive must select another socket. The Proposition 65 notice applies to the coating material used on this specific part.

Questions about this item
Should I choose the 12 mm size or another metric size for my 3/8 in drive?
The 5-3312 is the 12 mm socket; other metric sizes are sold separately under their own part numbers.
How does the 360-degree rotation help when I am working in a real engine bay?
The universal joint lets the socket pivot freely so you can reach fasteners at awkward angles without binding the ratchet.
What does the ASME B107.110 standard mean for daily impact-wrench use?
It confirms the socket meets the industry dimensional and strength requirements for 3/8 in drive impact applications.
