Socket Bit GEKO 9.0 mm long for 1/2" drive, CrV (model T00144-09)

Long 9.0 mm socket bit from GEKO designed for 1/2" square drive tools, manufactured from chromium-vanadium (CrV) steel. The extended-length socket bit combines a 9.0 mm hex/contact profile with a long shank to reach recessed fasteners and work in confined areas. It is suitable for use with ratchets, torque wrenches and impact drivers that accept a 1/2" drive and is intended for automotive repair, mechanical maintenance and assembly tasks where extra reach and a durable material are required.

Advantages

The CrV steel construction offers improved toughness and resistance to wear compared with standard carbon steel, providing longer service life under repeated torque and impact. The long shank increases accessibility to recessed or obstructed fasteners without the need to disassemble surrounding components. The standard 1/2" square drive interface ensures compatibility with a wide range of hand and power drive tools commonly used in workshops and garages.

Suitable for

• Automotive repairs and tightening or loosening wheel and engine fasteners in recessed positions
• Mechanical and industrial maintenance tasks requiring extended reach
• Assembly work where bolts are located in deep or confined housings
• Use with 1/2" drive ratchets, torque wrenches and compatible impact drivers

Key specifications

• Nominal socket size: 9.0 mm
• Drive interface: 1/2" square drive compatibility
• Material: chromium-vanadium (CrV) steel
• Design: long shank/socket bit for extended reach
• Typical applications: recessed fasteners, tight spaces, automotive and mechanical use

How to use

Select a compatible 1/2" drive ratchet, torque wrench or impact driver and securely attach the long 9.0 mm socket bit to the tool’s square drive. Position the socket bit over the fastener head, ensuring proper engagement before applying torque. For torque-critical fasteners, use a calibrated torque wrench and apply the manufacturer-specified torque. When using impact drivers, verify the bit and tool are rated for impact use and apply short controlled bursts to avoid rounding fastener heads.

Usage recommendations

Inspect the socket bit for wear or deformation before use and avoid excessive side loading that could cause breakage. Clean and lightly lubricate the drive interface periodically to prevent corrosion and ensure smooth fit with the 1/2" drive. Store the bit in a dedicated holder to protect the working end and maintain accurate fit to fasteners.
