## Summary description

Proline hex Allen socket bit for 1/2" drive, size H7 with a length of 140 mm.

## Long description

Proline Hex Allen Socket Bit 1/2" H7 x 140mm is a solid-drive tool intended for use with 1/2" ratchets and extensions. With a H7 hex profile and a 140 mm overall length, the bit provides extended reach for recessed or hard-to-access hex fasteners. It is compatible with standard 1/2" square drives and is suited for applications in automotive repair, mechanical assembly and general maintenance where a robust hex bit and additional reach are required.
Advantages
The hex Allen socket bit is manufactured to provide a precise fit on H7 hex fasteners, reducing slippage and rounding of screw heads. Its 1/2" drive interface ensures secure connection to ratchets and extensions for higher torque transfer. The 140 mm length offers improved accessibility in deep or confined spaces while maintaining sufficient stiffness for controlled torque application.
Suitable for
 Automotive repairs involving hex bolts and set screws
 Mechanical assembly and disassembly tasks
 Maintenance work in workshops and industrial settings
 Situations requiring extended reach with a 1/2" drive
Key specifications
 Hex size: H7
 Drive type: 1/2" square drive
 Overall length: 140 mm
 Material: hardened tool steel (manufacturing standard for solid socket bits)
 Profile: internal hex (Allen / imbus) socket
How to use
Insert the hex Allen socket bit into a compatible 1/2" ratchet, breaker bar or extension. Engage the hex profile fully with the fastener to avoid cam-out; apply steady torque while keeping the bit aligned with the screw axis. For tightening, turn until the required torque is reached; for loosening, apply controlled force to prevent rounding. If using with an extension, ensure the connection is secure before applying high torque.
Usage recommendations
Use the bit with tools rated for 1/2" drives and avoid impact use unless the bit and tool are specified for impact applications. Inspect the hex profile and drive connection for wear before use and replace the bit if deformation or excessive wear is present. For precision torque requirements, use a torque wrench with the appropriate adapter.
