Impact Socket Deep 1" 42mm 6-Point – JCB

Deep impact socket for 1" drive tools, 42 mm diameter, 6‑point configuration from JCB. Designed for use with impact wrenches and heavy‑duty torque applications, this 42 mm deep socket gives access to recessed fasteners while maintaining secure engagement across six contact faces. The socket is intended to withstand the loads and vibrations typical of industrial, automotive, and construction work and fits standard 1" drive air, electric and battery impact tools.

Advantages

The 6‑point geometry concentrates force on the flats of fasteners to reduce rounding and ensure stable torque transfer. Its deep design enables reach to bolts and nuts set below flanges or inside housings. Manufactured for impact use, the socket is heat treated and finished to resist wear and tolerate repeated high‑torque cycles. Compatibility with 1" drive impact tools makes it suitable for heavy equipment and professional workshops.

Suitable for

• Removing and tightening large hex bolts on construction machinery
• Wheel nut and axle work on heavy commercial vehicles
• Maintenance of agricultural and earthmoving equipment
• Industrial assembly and service tasks requiring high torque

Key specifications

• Drive size: 1 inch
• Socket size: 42 mm
• Point configuration: 6‑point (hex)
• Depth: deep profile for recessed fasteners
• Intended use: impact service with impact wrenches
• Material and treatment: heat‑treated steel suitable for impact loading

How to use

Select a compatible 1" drive impact wrench or adaptor and ensure the tool is rated for the torque required by the fastener. Fit the 42 mm deep impact socket squarely onto the fastener head, making sure the six faces seat fully on the flats. When operating the impact wrench, apply steady, controlled bursts rather than continuous full‑power holds to avoid over‑torquing. After use, inspect the socket for cracks, rounding, or excessive wear before storing.

Usage recommendations

Use with appropriate impact‑rated accessories only; do not use deep impact sockets on hand ratchets or torque wrenches for final torque unless specified by the wrench manufacturer. Regularly clean and inspect the socket and replace if deformation or cracks are detected. Store in a dry place to minimise corrosion and maintain service life.
