Thank you for viewing my listing from among many others. This is a set of 14 deep sockets from MAC TOOLS, ranging from 6mm to 19mm, along with a socket holder (OEM by MTS) with the MACTOOLS logo. I was transferred to a different department shortly after purchasing these, so the number of times I used them is extremely low. Socket Description: The patented 6-point non-slip design allows you to turn 85% of bolts/nuts that have been stripped by offsetting the line from the center. Each socket uses MAC-TOOLS quality steel. Large size markings with good visibility are used to improve workability. Caution: Chrome sockets and attachments must be used manually. Socket Holder Description: The strong magnetic base made of nitrile rubber holds the socket organizer and sockets during work or in the toolbox. The strong magnetic force securely holds the sockets. Vertical type for deep drawers. Horizontal type for shallow drawers. Easy to quickly find the correct size, and very easy to put in and take out sockets. Please refrain from purchasing if you are sensitive to used items.
