King Tony 4435M 1/2" Drive Long Impact Socket 21 mm

The King Tony 4435M is a professional-grade 1/2" drive long impact socket, specifically engineered for high-torque applications where durability and precision are paramount. With a 21 mm metric size and a robust construction made from chrome-molybdenum alloy steel, this socket is designed to withstand the intense forces generated by impact wrenches. Its 80 mm length offers extended reach, allowing users to access fasteners in deep or confined spaces that standard sockets cannot reach.

Advantages

This impact socket features a specialized phosphate sunk finish that provides superior resistance to corrosion and wear, ensuring a long service life even in demanding industrial environments. The 6-point design ensures a secure grip on hexagonal fasteners, minimizing the risk of rounding off bolt heads during high-torque operations. Its heavy-duty construction meets DIN 3121 standards, guaranteeing reliability and safety for professional mechanics and industrial technicians who require consistent performance under pressure.

Suitable for

• Automotive repair and maintenance
• Industrial machinery assembly and disassembly
• Heavy equipment servicing
• Work in deep or recessed engine bays

When it may not be suitable

This socket is not intended for use with standard hand tools where high-impact resistance is not required, as its heavy-duty design may be bulkier than necessary for light-duty tasks. It is also not compatible with fasteners that do not match the 21 mm metric size or with drive systems other than the 1/2" standard.

Key specifications

• Drive size: 1/2 inch
• Socket size: 21 mm
• Length: 80 mm
• Material: Chrome-molybdenum alloy steel
• Finish: Phosphate sunk
• Design: 6-point deep socket
• Weight: 240 g

How to use

To use the King Tony 4435M, attach the socket securely to the 1/2" square drive anvil of your impact wrench. Ensure the socket is fully seated on the fastener head before activating the tool. Always use appropriate safety gear, including eye protection, when operating impact tools. After use, clean the socket to remove debris and store it in a dry environment to maintain the integrity of the phosphate finish.

What to consider before purchase

• Verify that your impact wrench has a 1/2" drive output.
• Confirm the fastener size is exactly 21 mm to prevent slippage.
• Ensure the 80 mm length is sufficient for your specific clearance requirements.

Usage recommendations

Regularly inspect the socket for signs of cracks or excessive wear, especially after heavy use. Avoid using chrome-plated sockets for impact applications, as this chrome-molybdenum tool is specifically heat-treated to absorb the shock of impact wrenches.
