Socket impact 3/4" 42 mm 6-point Corona JCB-46542

Corona impact socket 3/4" 42 mm 6-point JCB-46542 is a purpose-built impact socket for high-torque fastening and loosening tasks. Intended for use with impact wrenches and pneumatic or electric tools, this 42 mm, 6-point design focuses on secure engagement with hex fasteners to minimise rounding and ensure consistent torque transfer. The socket is suited to professional environments such as automotive repair, construction sites and industrial maintenance where durable, repeatable performance is required.

Advantages

The 6-point geometry concentrates contact on the flat sides of fasteners to reduce slippage and protect bolt heads under heavy torque. The 3/4" drive size provides compatibility with common impact wrenches used in workshop and field settings. Manufactured for impact use, the socket is designed to withstand repeated shock loads and to offer reliable fitment for 42 mm hex fasteners. Its configuration supports quick attachment to power tools and stable operation during high-torque cycles.

Suitable for

• Automotive repair: wheel nuts, suspension and drivetrain components.
• Construction and assembly: structural bolts and heavy machinery fasteners.
• Industrial maintenance: plant equipment and mechanical servicing.
• Field service work: mobile tool kits and on-site heavy-torque applications.

Key specifications

• Drive size: 3/4 inch.
• Socket size: 42 mm across flats.
• Point configuration: 6-point (hex).
• Intended use: impact-rated for pneumatic and electric impact tools.
• Application: designed for high-torque fastening and loosening.

How to use

Select the 42 mm 6-point socket and attach it firmly to a compatible 3/4" drive impact wrench. Ensure the fastener and socket are aligned squarely before applying power. Apply short bursts of torque when breaking loose tight fasteners and maintain controlled operation when tightening to avoid over-torquing. After use, inspect the socket for visible wear or deformation and store it dry to prevent corrosion.

Usage recommendations

Use appropriate personal protective equipment and follow tool manufacturer torque guidelines. For repetitive high-torque jobs, periodically check the socket for cracking or rounding and replace if any damage is found. When precision torque is required, finish fasteners with a calibrated torque wrench rather than relying solely on an impact tool.
