4-Tab Lockring Socket
The 4 lockring socket tabs should be slightly wider to provide a more snug fit in the lockring slots. The socket is also too shallow, engaging only about half the thickness of the lockring. Finally, the 1/2 inch drive hole is only about 2 mm thick so that the socket wobbles significantly on the drive. All three of these issues makes it difficult to provide 100 lb-ft of torque without the socket wobbling and losing grip on the lockring.
