Socket 1/2" 6-point STANLEY STMT72947-8B 22 mm

STANLEY 1/2" 6-point socket STMT72947-8B, size 22 mm, is a compact hand tool designed for use with 1/2-inch drive ratchets and breakers. The six-point design ensures direct contact with the flats of hex fasteners to reduce rounding and improve torque transfer. The socket's metal construction provides durability for repeated use in automotive, mechanical and maintenance tasks where reliable fit and controlled torque application are required.

Advantages

The 6-point geometry minimizes slippage and distributes force evenly across fastener flats, reducing the risk of damaging bolt heads. A 1/2" drive compatibility makes the socket suitable for higher-torque applications compared with smaller drives. The 22 mm size covers a common range of metric fasteners encountered in vehicle maintenance and machinery servicing. Its compact construction allows easier access in confined spaces and convenient storage in toolkits.

Suitable for

• Automotive repair and wheel/engine fasteners
• General mechanical maintenance and assembly
• Industrial and workshop use with impact or breaker bars (with appropriate drive tools)
• Plumbing and HVAC tasks requiring metric sockets

Key specifications

• Drive size: 1/2 inch
• Point configuration: 6-point (hex)
• Socket size: 22 mm
• Material: metal alloy construction designed for durability
• Finish: corrosion-resistant surface treatment for extended service life
• Length: compact profile for access in tight spaces

How to use

Select a compatible 1/2" drive ratchet, breaker bar or torque wrench and attach the 22 mm socket by pushing it onto the drive square until it engages. Place the socket over the hex fastener ensuring full contact with the flats, then apply torque in the intended direction. For removal, reverse the drive direction. Use controlled, steady force to avoid sudden slips. When using with impact tools, confirm the socket and drive tool are rated for impact use before operation.

Usage recommendations

Use the socket with the correct 1/2" drive tool and appropriate torque settings for the application. Inspect the socket regularly for wear or rounding; replace if deformation or cracking is observed. Store in a dry place and keep the drive square clean and lightly lubricated for reliable engagement.
