Socket 12-Point 1/2" CR-V 17 mm GEKO G12217

12-point 1/2" drive socket GEKO G12217 is a 17 mm socket manufactured from chrome-vanadium (CR-V) steel for use with 1/2" drive ratchets, breaker bars and torque tools. It is intended for engaging 12-point fastener profiles and provides compatibility with a wide range of hexagonal and double-hexagonal bolts and nuts commonly found in automotive and mechanical applications. The socket’s construction focuses on balanced hardness and toughness to withstand repeated torque cycles in workshop environments.

Advantages

The 12-point geometry allows easier alignment with fasteners in confined spaces and enables engagement on both hex and double-hex heads. Manufactured from chrome-vanadium steel, the socket offers good resistance to wear and deformation under torque. The 1/2" drive interface ensures secure attachment to standard ratchets and torque tools, while the 17 mm nominal size matches common metric fasteners used in vehicle repair and mechanical maintenance.

Suitable for

• Automotive repair and maintenance where 17 mm fasteners are used
• Mechanical and industrial maintenance tasks requiring 1/2" drive tools
• General workshop use for assembly and disassembly of machinery
• Situations with limited access where 12-point sockets ease alignment

Key specifications

• Drive size: 1/2" (12.7 mm)
• Socket profile: 12-point
• Nominal socket size: 17 mm
• Material: chrome-vanadium (CR-V) steel
• Typical applications: ratchets, breaker bars, torque wrenches

How to use

Select the 17 mm socket and attach it to a compatible 1/2" drive ratchet, breaker bar or torque tool. Place the socket squarely onto the fastener head, ensuring full engagement of the 12-point profile before applying turning force. Apply torque gradually and avoid sudden impacts beyond the tool’s rated limits. For torque-critical fasteners use a calibrated torque wrench and follow the manufacturer’s specified torque values.

Usage recommendations

Inspect the socket for cracks or rounded corners before use. Keep the working surfaces clean and lightly lubricated if needed to reduce wear. Store sockets in a designated holder to prevent damage and to maintain quick access. Use impact-rated sockets for repeated heavy impact applications; this 12-point CR-V socket is intended for standard hand-tool torque use unless explicitly marked as impact-rated.
