Socket 1/2" 27 mm Hartsson 17A327, 6-point drive

Hartsson 17A327 is a 6-point socket with a 1/2" drive and a 27 mm size, engineered for direct engagement with hexagonal nuts and bolts. It is compatible with 1/2" ratchets, torque wrenches and other hand tools commonly used in automotive repair, mechanical assembly and routine maintenance. The 6-point profile is intended to reduce rounding on fasteners by contacting flats rather than corners, and the 1/2" drive provides sufficient torque transfer for medium to heavy fastening tasks.

Advantages

The 6-point configuration offers improved grip on hex fasteners and minimizes the risk of slippage under load. A 27 mm working size ensures precise fit to standard metric fasteners of that dimension. The 1/2" drive interface delivers robust torque capacity and broad compatibility with widely used ratchets and torque tools. The socket's construction is designed for durable performance in workshop and field environments.

Suitable for

• Automotive wheel and suspension fasteners sized 27 mm
• Engine and transmission maintenance where 27 mm hex bolts are used
• General mechanical assembly and disassembly requiring a 1/2" drive
• Workshop and industrial maintenance tasks demanding reliable torque transfer

Key specifications

• Drive size: 1/2" (square drive)
• Socket profile: 6-point (hexagonal)
• Working size: 27 mm
• Intended use: fastening and loosening hexagonal nuts and bolts
• Compatibility: designed for use with 1/2" ratchets, torque wrenches and compatible hand tools

How to use

Select the Hartsson 27 mm, 6-point socket and fit it onto a compatible 1/2" drive tool such as a ratchet or torque wrench. Ensure the socket fully seats on the fastener flats before applying torque to prevent rounding. For tightening to a specific torque value, use a calibrated torque wrench and apply force steadily until the target torque is reached. When loosening seized or corrosion-affected fasteners, apply penetrating lubricant and use controlled force to avoid sudden breakaway.

Usage recommendations

Inspect the socket for damage or wear before each use and replace if deformed or cracked. Use the correct 6-point socket size rather than a larger or worn tool to reduce fastener damage. Store the socket in a dry, organized tool set to prolong service life and maintain compatibility with 1/2" drive accessories.
