Impact Socket 1/2" 6-point 27mm CR-MO by Tvardy

Tvardy Impact Socket 1/2" 6-point 27mm CR-MO is a single-piece impact socket designed for use with impact wrenches and impact drivers. Machined with a 6-point hex profile and a 27 mm opening, the socket is manufactured from chromium-molybdenum (CR-MO) steel to increase toughness and resistance to repeated shock loads. The design delivers a secure engagement with hex fasteners and can withstand the demands of automotive, industrial maintenance, and heavy repair applications.

Advantages

The CR-MO construction provides higher toughness and improved resistance to cracking under impact compared with standard alloy sockets. The 6-point profile concentrates contact area on the flats of fasteners to reduce rounding and slipping. The 1/2" drive size offers compatibility with a wide range of professional impact tools, and the solid one-piece design minimises deforming under high torque. The socket’s 27 mm size covers common fasteners found in wheel, suspension and machinery maintenance.

Suitable for

• Removal and tightening of 27 mm hex fasteners using a 1/2" impact wrench or driver
• Automotive wheel, suspension and drivetrain service where impact tools are used
• Industrial maintenance and heavy-duty repair tasks requiring high-impact resistance
• Professional workshops and service garages using pneumatic or electric impact tools

When it may not be suitable

This impact socket is intended for use with impact-rated tools and high-torque applications; it is not optimized for delicate hand-torque tasks where a non-impact chrome-plated socket would be preferable to avoid over-tightening. It is also not designed for use on fasteners with damaged or rounded heads where extractor-type tools would be required.

Key specifications

• Drive size: 1/2 inch
• Socket profile: 6-point (hex)
• Nominal size: 27 mm
• Material: Chromium-molybdenum (CR-MO) steel
• Intended use: Impact/pneumatic and electric impact tools
• Construction: Single-piece impact socket

How to use

Select the 27 mm 6-point impact socket and attach it securely to a compatible 1/2" impact wrench or driver. Ensure the tool’s anvil and the socket’s square bore are free of debris before use. Fit the socket squarely onto the fastener flats to ensure full contact, then apply controlled impact torque according to the fastener and equipment specifications. After use, inspect the socket for cracking or excessive wear and store it in a dry tool chest.

What to consider before purchase

• Confirm that your impact tool has a 1/2" drive to match this socket
• Verify that 27 mm is the correct size for your fasteners
• Consider whether a 6-point profile is preferable for your fastener condition versus a 12-point socket
• Note that CR-MO sockets are intended for impact use and may have a darker finish compared with chrome-plated hand sockets

Usage recommendations

Use this CR-MO 6-point 27 mm impact socket with properly maintained impact tools, apply torque within the tool and fastener ratings, and replace the socket if any cracks or deformation appear to maintain safe operation.
