Monster Tools has introduced two new XXL 12-inch swivel socket sets.

The new sets are the MST99777 11-piece metric set and MST99789 10-piece SAE set. Made of chromoly forged steel with black oxide coating, these sets are built for the professional automotive service technician.

Featuring a 30-degree swivel head for more usable torque than universal joint designs. The pin-less joint design prevents binding and is safer than traditional universal joint designs. These swivel socket sets also come with a lifetime warranty. Monster products are available exclusively through the mobile tool distribution channel.
