Socket, impact 1/2" 6-point 19 mm CR-MO by Tvardy

Tvardy impact socket 1/2" 6-point 19 mm CR-MO is a purpose-built socket intended for use with impact wrenches and pneumatic tools. Manufactured from chromium-molybdenum steel, this 19 mm 6-point socket is engineered to withstand repeated shock loads and high torque during fastening and removal of nuts and bolts in automotive, industrial and maintenance environments.

Advantages

The CR-MO construction provides enhanced toughness and resistance to fracturing under impact compared with standard chrome-vanadium alloys. The 6-point profile grips fasteners on the flats to reduce rounding, while the 1/2" (12.7 mm) drive size is compatible with most common impact wrench models. The socket’s geometry and material selection are optimized for shock absorption and long service life in high-torque applications.

Suitable for

• Automotive repair and wheel nut removal
• Industrial assembly and maintenance with impact tools
• Workshops using pneumatic or electric impact wrenches
• Tasks requiring a durable 19 mm socket for high-torque fastening

When it may not be suitable

This impact socket is not intended for use with hand-only ratchets or low-clearance situations where a thin-walled or swivel socket is required. It is specifically designed for impact tool use; using it on non-impact tools may not take advantage of its shock-resistant properties and could lead to improper fit or accelerated wear.

Key specifications

• Drive size: 1/2" (12.7 mm)
• Socket size: 19 mm
• Point profile: 6-point (hex)
• Material: chromium-molybdenum (CR-MO) steel
• Designed use: impact wrench and pneumatic tool applications
• Suitable torque range: high-torque, shock-load environments

How to use

Attach the 1/2" drive of the socket to a compatible impact wrench or adapter, ensuring a secure connection. Position the 6-point socket squarely on the fastener flats to prevent rounding, then apply the impact tool at controlled speed and torque settings appropriate for the fastener and assembly. After use, inspect the socket for cracks or deformation before storage and avoid using it on damaged or rounded fasteners.

What to consider before purchase

• Confirm your tool’s drive size is 1/2" (12.7 mm) for compatibility.
• Verify 19 mm is the correct fastener size for your application.
• Consider whether an impact-rated CR-MO socket is required versus a standard socket.
• Check workspace clearance and whether a standard-length socket fits the application.

Usage recommendations

Use the socket exclusively with impact-rated tools and accessories, keep connections clean and free of debris, and replace the socket if any signs of crack, chip or excessive wear appear to maintain safe and reliable operation.
