## Summary description

YATO YT-12939 is a single socket driver bit with a 12-point shank for secure engagement. It features a 25.4 mm (1/2") shank size and an overall length of 77 mm. Supplied as one piece, this bit is suited for use with compatible 1/2" drives in automotive, mechanical and maintenance tasks where a 12-point interface is required.

## Long description

YATO YT-12939 is a single socket bit with a 12-point profile designed for secure engagement with fasteners that require multiple contact faces. The bit has a 1/2" (25.4 mm) drive shank and an overall length of 77 mm, providing a balance between reach and torque transmission for workshop and field use. Supplied as one piece, this socket bit is intended for use with compatible 1/2" drive tools in automotive repair, mechanical maintenance and general service applications.
Advantages
The 12-point geometry enables easier alignment with bolts and nuts in confined spaces and helps distribute force across more contact surfaces to reduce rounding. The 1/2" (25.4 mm) drive shank ensures compatibility with a wide range of ratchets, torque wrenches and impact adapters that accept standard half-inch drives. The 77 mm length gives additional reach without sacrificing control, while the single-piece design simplifies inventory and replacement.
Suitable for
Automotive fastener removal and installation
Mechanical and industrial maintenance tasks
Workshop repairs where a 12-point interface is preferred
Use with 1/2" drive ratchets, torque wrenches and impact adapters
Key specifications
Contact profile: 12-point
Drive shank size: 1/2" (25.4 mm)
Overall length: 77 mm
Quantity: 1 piece
How to use
Select a compatible 1/2" drive tool and insert the socket bit into the tool’s square drive until it seats securely. Position the bit onto the fastener, ensuring full engagement of the 12-point profile before applying torque. When loosening fasteners, apply steady, controlled force to avoid slipping; when tightening with a torque wrench, set the required torque value and apply force until the wrench indicates the set value. After use, clean the bit of debris and store it in an appropriate holder to prevent damage.
Usage recommendations
Use the bit with tools rated for the intended torque and consider a 6-point profile for high-torque applications where maximum contact is required. Inspect the bit for wear or deformation before each use and replace it if the contact surfaces show rounding or damage.
