Socket bit 1/2" 6-point 9 mm MODECO MN-55-109

Modeco MN-55-109 is a 1/2" drive, 6-point 9 mm socket bit designed for reliable engagement with hex-head bolts and nuts. It is intended for use with compatible 1/2" ratchets, torque wrenches and extensions and provides a compact solution for fastening and loosening operations in automotive, mechanical and general maintenance work.

Advantages

The 6-point geometry reduces rounding of fasteners by concentrating torque on the flats rather than the corners, while the 1/2" drive interface ensures compatibility with standard half-inch hand tools. The 9 mm internal diameter fits common small-to-medium hex fasteners used in vehicles and machinery. The socket bit construction offers straightforward attachment and removal, and its solid design supports accurate torque transfer when used with calibrated tools.

Suitable for

• Automotive repairs and maintenance — engine, chassis and accessory work
• Mechanical assembly and disassembly of equipment and components
• Workshop and garage tasks requiring a 9 mm hex socket
• General maintenance and repair jobs in industrial and home settings

Key specifications

• Drive size: 1/2" (half-inch)
• Socket profile: 6-point (hex)
• Internal size: 9 mm
• Compatible with: 1/2" ratchets, torque wrenches and extensions
• Intended use: fastening and loosening hex-head bolts and nuts

How to use

Select a compatible 1/2" drive tool and attach the socket bit securely to the square drive. Place the 9 mm hex opening over the bolt or nut ensuring full seating on the flats. Apply turning force using a ratchet or torque wrench as required; when precise torque is needed, use a calibrated torque wrench and follow the fastener manufacturer’s torque specification. Remove the socket by pulling it off the drive once the operation is complete.

Usage recommendations

Inspect the fastener and socket for wear or damage before use. Use the appropriate torque settings for the application to avoid overloading the bit or fastener. Store the socket bit in a dry tool case to prevent corrosion and maintain fit accuracy.
