Socket wrench insert 3/4" 38 mm (6-point) JCB JCB-46538

JCB Socket wrench insert 3/4" 38 mm (6-point) is an impact-rated 3/4-inch drive socket designed for high-torque fastening and loosening of hexagonal nuts and bolts. The 38 mm diameter and six-point profile ensure a positive grip on fastener flats for efficient torque transfer while reducing the risk of rounding. Manufactured for durability, this insert is suitable for repeated use with impact wrenches and breakers in automotive, construction, and industrial maintenance environments.

Advantages

The six-point geometry delivers secure engagement with hexagonal fasteners, minimising slippage under heavy loads. Built for impact applications, the socket insert resists deformation and cracking when used with pneumatic or electric impact tools. Its 3/4-inch drive compatibility allows connection to a wide range of professional impact wrenches and breakers, providing reliable torque transfer and extended service life in demanding work conditions.

Suitable for

• Automotive wheel and suspension maintenance
• Construction equipment servicing and assembly
• Industrial machinery maintenance and repair
• Heavy vehicle and agricultural equipment fastening

Key specifications

• Drive size: 3/4 inch
• Socket diameter: 38 mm
• Point profile: 6-point (hex)
• Intended use: impact applications with impact wrenches and breakers
• Material and finish: impact-rated hardened steel with protective surface treatment

How to use

Attach the 3/4" drive of the socket insert to a compatible impact wrench or breaker, ensuring the detent or locking mechanism on the tool secures the insert. Position the 6-point socket fully onto the hex fastener, then operate the impact tool following manufacturer torque and safety guidelines. Inspect the socket for damage or wear before each use and replace if cracking, excessive rounding, or other deformation is present.

Usage recommendations

Use with impact-rated extensions and universal joints only; avoid using hand ratchets or cheater bars with impact sockets. Wear appropriate eye and hand protection, and follow torque specifications for the fastener to prevent over-tightening. Store the socket clean and dry to preserve the protective finish and check regularly for signs of wear.
