Impact Socket 1/2" 6-Point 13 mm CR-MO Tvardy

The Tvardy Impact Socket 1/2" 6-Point 13 mm CR-MO is a heavy-duty socket engineered for use with impact wrenches and impact drivers. Made from chrome-molybdenum (CR-MO) steel, this 13 mm six-point socket provides a secure fit on hex fasteners and is designed to withstand the repeated high torque of pneumatic and electric impact tools. Its construction emphasizes strength and resistance to rounding or cracking under load, making it suitable for automotive repair, mechanical maintenance and industrial fastening tasks.

Advantages

This impact socket combines CR-MO alloy strength with a six-point geometry to reduce fastener rounding and improve torque transfer. The 1/2" drive interface is compatible with standard impact tools, and the 13 mm size meets common metric fastener requirements. The socket’s material and heat treatment provide enhanced toughness and fatigue resistance compared with standard chrome-vanadium hand sockets.

Suitable for

• Automotive repair and wheel or suspension work
• General machinery and equipment maintenance
• Industrial assembly and heavy-duty fastening jobs
• Use with pneumatic and electric impact wrenches and drivers

When it may not be suitable

This impact socket is intended specifically for impact applications; it is not optimized for precision torque measurement or delicate assembly where torque control and finish protection are required. For very small or non-standard fasteners, or for tasks requiring a thin-wall profile, a different socket design may be more appropriate.

Key specifications

• Drive size: 1/2" (square drive)
• Socket geometry: 6-point (hex)
• Nominal size: 13 mm
• Material: chrome-molybdenum (CR-MO) steel
• Intended use: impact applications with pneumatic or electric impact tools

How to use

Select the 13 mm six-point impact socket and attach it firmly to a compatible 1/2" drive impact wrench or driver. Ensure the socket is fully seated on the fastener before applying impact torque to reduce the risk of slippage. Operate the impact tool following the tool manufacturer’s recommendations for speed and torque settings. After use, inspect the socket for signs of wear or cracking and replace if any damage is present to maintain safety and performance.

What to consider before purchase

• Verify that a 1/2" drive and a 13 mm socket size match your fasteners and impact tool.
• Confirm the need for an impact-rated CR-MO socket rather than a standard hand socket.
• Consider whether a six-point geometry is preferable to a twelve-point for your fastener access and contact requirements.

Usage recommendations

Use this CR-MO impact socket with properly rated impact tools and appropriate personal protective equipment. Avoid using impact sockets on non-impact hand tools and replace the socket if deformation or cracks are observed to ensure reliable performance and safety.
