Choose the Correct Fit
Check the listed metric sizes against your fasteners. The size range summarizes the set and does not promise every intermediate size.
Match the 3/8-inch square drive to your impact tool or adapter. Seat the socket fully and verify retention before use.
Installation & Care
Choose the depth to suit the fastener recess and any protruding stud. Check clearance for both the socket body and the attached tool.
Clean and inspect sockets after use. Keep the set together and replace any socket with cracks, distortion or badly worn corners.

Important Product Questions
Which socket sizes are included?
Metric: 10, 13, 14, 15, 17, 19, 21 mm. A 3/8-inch socket adapter is included.
Does the piece count equal the socket count?
This set contains 7 deep sockets and 1 accessory. The storage rail is supplied for organization.
Will the sockets fit any impact tool?
They use a 3/8-inch square drive. Match that drive and the retaining arrangement to your tool; an adapter does not remove the tool or accessory limits.
