## Long description

Teng Tools hex bit socket for 1/4" drive, designed for use with ratchets and bit holders to install and remove 4 mm internal hex fasteners. The 4 mm long-profile bit socket provides additional reach to access recessed or confined fasteners while maintaining compatibility with standard 1/4" drive tool systems. Constructed to fit typical mechanical, electrical and assembly tasks that require a compact hex interface.
Advantages
The hex bit socket features a long-profile 4 mm hex head that allows access to recessed screws and bolts without the need for extended adapters. Its 1/4" drive interface ensures compatibility with a wide range of ratchets, extensions and bit holders. The compact design delivers improved tool control in tight spaces while enabling quick exchange between sockets and bits. Material selection and manufacturing tolerances provide reliable seating on fasteners and consistent performance during repeat use.
Suitable for
 Installing and removing 4 mm internal hex fasteners in mechanical assemblies
 Electrical panel work and appliance servicing requiring compact access
 General assembly and maintenance where recessed or tight fasteners are present
Key specifications
 Drive size: 1/4"
 Bit type: internal hex (4 mm)
 Profile: long/extended for recessed access
 Compatibility: fits standard 1/4" ratchets, extensions and bit holders
 Intended applications: mechanical, electrical, assembly and maintenance tasks
How to use
Select a 1/4" drive ratchet or bit holder and attach the hex bit socket securely to the drive. Align the 4 mm hex head with the internal hex fastener and apply steady torque, taking care not to exceed the recommended torque for the fastener material. For recessed or deep-set fasteners, use the extended reach of the long-profile socket to engage the hex fully before turning. After use, clean any debris from the socket and store with other 1/4" drive tools to maintain accessibility.
Usage recommendations
Use the hex bit socket with hand tools designed for 1/4" drive systems and avoid applying impact or excessive torque beyond the fastener’s specifications. Inspect the socket before use for wear or damage and replace if the hex profile shows rounding to prevent fastener damage. For best results, pair with appropriate extensions or universal joints when working at difficult angles.
