Socket 1/2" 12-point 12 mm Hartsson model 17C312Z

Hartsson Socket 1/2" 12-point 12 mm model 17C312Z is a compact hand tool accessory designed for 1/2" drive ratchets and torque wrenches. The 12-point internal profile allows engagement with hex fasteners in tight or confined spaces and enables quicker indexing than a 6-point socket. This 12 mm socket is intended for mechanical work requiring a durable and accurately sized attachment for standard metric fasteners.

Advantages

The 12-point design provides more contact positions for faster repositioning on the fastener without removing the tool. Made for a 1/2" square drive, the socket is compatible with common ratchets and torque wrenches used in automotive and industrial maintenance. Its 12 mm size ensures precise fit on metric hex bolts and nuts, reducing the risk of rounding. The socket's compact length is suitable for working in constrained areas where reach and clearance are limited.

Suitable for

• Automotive repair and servicing
• Machinery maintenance and assembly
• General mechanical and workshop tasks
• Tight or confined spaces where frequent repositioning is needed

Key specifications

• Drive size: 1/2" square drive (compatible with 1/2" ratchets and torque wrenches)
• Internal profile: 12-point
• Socket size: 12 mm
• Intended use: metric hex fasteners (bolts and nuts)
• Form factor: compact/standard length suitable for confined spaces

How to use

Select the 12 mm socket and attach it securely to a 1/2" drive ratchet or torque wrench. Engage the socket onto the fastener squarely to ensure maximum contact and avoid slipping. For tightening to a specific torque, use a compatible torque wrench and apply gradual force until the desired torque value is reached. When working in tight spaces, use the 12-point indexing to reposition the ratchet frequently without removing the socket.

Usage recommendations

Inspect the socket for wear or damage before use and avoid applying impact loads unless the socket is rated for impact use. Use appropriate personal protective equipment and the correct torque settings for fasteners to prevent over-tightening or damage.
