Socket impact 1/2" 6-point 18 mm CR-MO — Tvardy

Impact socket 1/2" 6-point 18 mm CR-MO by Tvardy is a heavy-duty socket designed for use with 1/2-inch drive impact wrenches and impact drivers. Manufactured from chrome-molybdenum (CR‑MO) steel, the 6-point (hex) profile distributes torque across flat surfaces of fasteners to reduce rounding and provide reliable engagement under high shock loads. The socket is suited for automotive repair, industrial maintenance and mechanical assembly where durable resistance to repeated impact and high torque is required.

Advantages

The CR‑MO steel construction offers increased toughness and fatigue resistance compared with standard chrome-vanadium sockets, making this 18 mm 6-point socket more resistant to deformation and cracking under repeated impact. The 6-point profile minimizes cam-out and protects fastener corners, improving torque transfer efficiency. Designed for impact applications, the surface finish and heat treatment are optimized to withstand shock loads from pneumatic and electric impact tools.

Suitable for

• Automotive wheel nut removal and installation
• Engine and chassis maintenance
• Industrial equipment assembly and disassembly
• Heavy machinery repair and routine maintenance
• Mechanical workshops and professional service bays

Key specifications

• Drive size: 1/2 inch drive compatibility
• Socket profile: 6-point (hex) configuration
• Nominal size: 18 mm
• Material: chrome-molybdenum (CR-MO) steel
• Designed for: impact wrench and impact driver use

How to use

Select the 18 mm 6-point impact socket and attach it securely to a 1/2" drive impact wrench or driver. Ensure the socket seats fully on the fastener head before applying torque. Use appropriate torque settings for the application and apply short bursts of torque rather than continuous high-speed operation when possible. Inspect the socket regularly for signs of wear, cracking, or deformation and replace it if damage is detected.

Usage recommendations

For safe and effective use, pair this impact socket with a compatible 1/2" impact extension or universal joint when access is restricted, and avoid using hand ratchets with impact-only sockets. Wear appropriate personal protective equipment and follow tool manufacturer guidelines for operating pressure and torque limits.
