Socket 1/2" 6-point 28 mm STANLEY 172551 (for hand and impact use)

STANLEY 172551 is a 6-point 1/2" drive socket in a 28 mm size, created for fastening and loosening hex fasteners in standard workshop and maintenance environments. The socket fits 1/2" drive ratchets and breakers and combines a precise 6-point profile with a durable finish to reduce rounding of nuts and support repeated use in automotive and mechanical tasks.

Advantages

The 6-point design provides secure contact with hexagonal fasteners, reducing the likelihood of slippage and rounding. Machined internal surfaces and accurate dimensions deliver reliable fitment on 28 mm bolts and nuts. The 1/2" drive interface is compatible with a wide range of hand and impact tools used in garages and industrial maintenance. A corrosion-resistant finish extends service life under typical workshop conditions.

Suitable for

• Automotive repairs—wheel and engine fasteners requiring a 28 mm socket
• Mechanical assembly and disassembly in workshops
• General maintenance tasks with 28 mm hex fasteners
• Use with 1/2" drive ratchets, breakers and impact tools

Key specifications

• Drive size: 1/2"
• Socket profile: 6-point (hex)
• Nominal size: 28 mm
• Intended use: hand and impact use
• Finish: corrosion-resistant surface treatment

How to use

Select a compatible 1/2" drive ratchet, breaker bar or impact wrench. Fit the 28 mm socket onto the tool's square drive and place it over the hex fastener. For tightening, apply steady torque until the required clamp is achieved; for loosening, reverse the drive direction and apply controlled force. Inspect the socket and fastener seating before applying high torque; replace the socket if visible wear or damage appears.

Usage recommendations

Use the socket within the recommended torque limits of your hand or impact tool. Avoid excessive hammering on the socket and do not use damaged sockets. Clean and lightly lubricate the drive connection after use to maintain fit and prevent corrosion.
