Socket 1/2" 12-point 20 mm STANLEY 1-17-063 (MPN 170631)

STANLEY 1/2" 12-point 20 mm socket is a hand tool accessory designed for use with 1/2-inch drive ratchets, torque wrenches and extensions. Its 12-point geometry enables easier engagement with hexagonal fasteners in confined or awkward spaces, reducing the need for precise alignment. The socket is intended for general mechanical, automotive and maintenance work where a 20 mm socket size is required.

Advantages

The 12-point configuration provides six additional contact positions compared with a 6-point design, which simplifies positioning on fasteners and speeds up repetitive work. Manufactured to fit standard 1/2-inch drive tools, the socket offers compatibility with a wide range of ratchets and extensions. The 20 mm size covers many common bolt and nut dimensions encountered in automotive and mechanical applications.

Suitable for

• Automotive maintenance and repairs
• General mechanical assembly and disassembly
• Workshop and field service tasks requiring a 20 mm socket
• Use with 1/2-inch drive ratchets, impact adapters, and extensions

Key specifications

• Drive type: 1/2-inch drive
• Point configuration: 12-point
• Socket size: 20 mm
• Compatibility: standard 1/2-inch drive ratchets and extensions
• Intended use: fastening and loosening 20 mm hex fasteners

How to use

Select the 20 mm socket for the corresponding fastener and attach it securely to a 1/2-inch drive ratchet, torque wrench, or extension. Place the socket squarely onto the fastener head, ensuring engagement on the 12 points. Apply controlled turning force appropriate to the fastener and tool being used, taking care when working with high torque to avoid rounding fastener edges.

Usage recommendations

Use the socket with the correct drive tool and observe torque specifications for the fastener. Inspect the socket for wear or damage before use and replace if rounded or cracked. For high-torque or impact applications, confirm the socket is rated for such use or use an impact-rated socket to ensure safety and longevity.
