## Long description

Proline 18664 is a Torx insert sized T55 with a 1/2" drive engineered for use with 1/2" ratchets, breaker bars or extension bars. The socket bit features a precisely formed Torx tip profile to engage Torx-head fasteners securely, reducing cam-out and distributing torque across the fastener. It is made for applications in automotive, industrial and mechanical repair where a durable 1/2" Torx accessory is required.
Advantages
The 1/2" T55 Torx socket bit offers accurate fit to Torx fasteners and reliable torque transfer for tightening and loosening operations. Its hardened tip and solid construction improve wear resistance and service life under repeated use. The half-inch drive interface ensures compatibility with common 1/2" hand tools and accessories, enabling use with ratchets, impact drivers (where appropriate), extensions and torque wrenches suitable for 1/2" drives.
Suitable for
Automotive repair and maintenance tasks requiring T55 Torx fasteners
Industrial assembly and disassembly of machinery with Torx-head screws
Mechanical and equipment servicing where 1/2" drive strength is needed
Professional workshops and advanced DIY projects
Key specifications
Tip profile: Torx (T55)
Drive size: 1/2" (half-inch)
Material and treatment: hardened steel tip; durable construction for repeated use
Compatibility: fits standard 1/2" ratchets, breaker bars, extension bars and compatible 1/2" accessories
How to use
Select the Proline 1/2" T55 Torx socket bit and attach it securely to a compatible 1/2" drive tool such as a ratchet, torque wrench or extension bar. Align the Torx tip with the fastener head before applying torque to avoid slipping. Apply steady, controlled force when tightening or loosening; when using a torque wrench, set the required torque value according to fastener specifications. Inspect the bit for wear or damage before use and replace if the tip shows rounding or deformation.
Usage recommendations
Use the socket bit with tools rated for 1/2" drive and appropriate torque limits. Avoid using excessive impact on non-impact-rated bits. Keep the bit clean and store in a dry place to extend service life. Replace the bit if the Torx profile becomes worn to prevent damage to fasteners.
