Socket 1/2" 12-point Hartsson 17 mm (model 17C317Z)

Hartsson 17 mm 12-point 1/2" socket (model 17C317Z) is a compact hand tool accessory designed for fastening and loosening hexagonal and bi-hexagonal fasteners. Produced as a 12-point socket with a 1/2" drive, it is compatible with standard 1/2" ratchets and torque wrenches. This socket is intended for tasks that require multiple engagement angles and improved access in confined spaces, commonly encountered in automotive, mechanical and maintenance work.

Advantages

The 12-point geometry allows for more frequent engagement with a fastener compared with 6-point sockets, enabling quicker repositioning in tight spaces. Its 1/2" drive compatibility ensures reliable connection to common ratchets and torque tools. The compact design helps reach recessed or hard-to-access fasteners while maintaining secure grip on hexagonal and bi-hexagonal heads. Constructed to withstand typical workshop torque requirements, the socket provides consistent contact and controlled torque transfer for routine fastening and loosening operations.

Suitable for

• Automotive repair and maintenance (engine bays, suspension, brakes)
• Mechanical assembly and disassembly tasks
• General workshop and field maintenance where confined access occurs
• Use with 1/2" ratchets and torque wrenches for controlled tightening

Key specifications

• Size: 17 mm
• Point count: 12-point design for multiple engagement positions
• Drive: 1/2" drive compatible with standard 1/2" ratchets and torque wrenches
• Intended fastener type: hexagonal and bi-hexagonal heads
• Form factor: compact socket profile for improved access in confined spaces

How to use

Select the 17 mm socket and attach it firmly to a 1/2" ratchet or torque wrench. Place the socket squarely onto the fastener head, ensuring full seating on the hexagonal or bi-hexagonal surface. Apply steady turning force to fasten or loosen the bolt or nut; when using a torque wrench, follow the specified torque values for the fastener. For removal or installation in restricted locations, reposition the ratchet as needed to engage the socket in the available clearance.

Usage recommendations

Inspect the socket before use for wear or damage and replace if any rounding or cracking is visible. Use hand tools rated for the required torque and avoid impact tools unless the socket is specified as impact-rated. Store the socket in a dry place and keep contact surfaces clean to maintain fit and performance.
