Choose the Correct Fit
Match the T55 tamper-proof torx tip to the fastener. Clear debris from the recess and seat the bit fully before turning.
Use a 3/8-inch drive hand tool and check that the socket is retained. Allow room for both the socket and handle travel.
Installation & Care
Keep the bit aligned with the fastener. Check for nearby parts that could deflect the socket before applying force.
Wipe the bit clean after use and store it dry. Replace a socket with a chipped, twisted or badly worn tip before continuing.

Important Product Questions
What should I check before choosing this socket?
Confirm the fastener uses a T55 tamper-proof torx recess and that your hand tool has a 3/8-inch drive. Check body clearance as well as tip fit.
Can I replace the bit separately?
This is a one-piece socket design. If the tip is damaged, choose a replacement socket rather than trying to separate the bit from its base.
Can I turn it with a wrench?
Yes. FOUR FLAT outer sides are wrench-compatible. Use a wrench that fits the flats securely; the bit size is not the external wrench size.
