Socket 12-point 1/2" 27 mm Hartsson 17C327Z

Hartsson 12-point 1/2" 27 mm socket is a tool designed for use with 1/2" drive ratchets and torque wrenches to tighten and loosen 27 mm hexagonal fasteners. The 12-point internal profile provides multiple engagement angles, making it easier to work in confined spaces and where swing clearance is limited. Constructed for general workshop, automotive, and maintenance applications, this socket is suitable for both professional mechanics and DIY users who require a reliable 27 mm socket for routine fastening tasks.

Advantages

The 12-point configuration allows re-engagement at smaller rotation increments compared with 6-point sockets, reducing the required swing arc when operating with a 1/2" ratchet. The socket is sized to fit standard 27 mm fasteners and designed to be compatible with common 1/2" drive tools, including torque wrenches, enabling controlled tightening to specified torque values. The design focuses on straightforward usability and accessibility in tight assemblies.

Suitable for

• Automotive repair and maintenance where 27 mm fasteners are used
• Industrial assembly and equipment servicing
• General workshop and home DIY projects requiring a 27 mm socket

Key specifications

• Drive size: 1/2 inch
• Socket profile: 12-point (double-hex)
• Nominal size: 27 mm
• Typical use: tightening and loosening hexagonal fasteners
• Compatibility: designed for use with 1/2" ratchets and torque wrenches

How to use

Select the Hartsson 27 mm 12-point socket and attach it firmly to a compatible 1/2" drive ratchet or torque wrench. Ensure the socket fully seats on the fastener before applying force to avoid rounding. For torque-controlled operations, use a calibrated torque wrench and set the required torque value, then apply force steadily until the wrench indicates the set torque. When working in confined spaces, use the 12-point profile to re-engage at smaller angles and reposition the ratchet as needed.

Usage recommendations

Inspect the socket before use for signs of wear or damage; replace if deformed or cracked. Use the correct drive tool and observe recommended torque values for fasteners to prevent over-tightening. Avoid using excessive impact tools unless the socket is rated for impact use.
