Impact deep socket 3/4" 49 mm (12-point) JCB

JCB impact deep socket, 3/4" drive with a 49 mm diameter and a 12-point internal profile engineered for use with impact wrenches and heavy-duty drivers. The deep design provides extended reach to access recessed nuts and bolts while the 12-point geometry allows quick alignment on fasteners in tight spaces. Constructed for professional applications in automotive repair, industrial maintenance and heavy equipment servicing where high torque and durability are essential.

Advantages

The impact-grade construction resists deformation under repeated high-torque use and is compatible with pneumatic and electric impact tools. The deep profile improves access to long studs and recessed fasteners, reducing the need for extensions. The 12-point configuration simplifies engagement on worn or rounded fasteners and allows for finer indexing in confined work areas. Surfaces are finished to reduce corrosion and ensure long service life under workshop conditions.

Suitable for

• Removing and tightening large nuts on commercial vehicles and heavy machinery
• Servicing suspension and drivetrain components with recessed fasteners
• Industrial maintenance tasks requiring high torque delivery
• Workshop and fleet maintenance where durable sockets are needed

Key specifications

• Drive size: 3/4 inch
• Socket diameter: 49 mm
• Point configuration: 12-point internal profile
• Type: deep socket for extended reach
• Intended use: impact applications with pneumatic or electric drivers

How to use

Select the 49 mm, 3/4" drive deep socket and attach it securely to a compatible impact wrench or driver. Position the socket squarely over the fastener and apply torque in short bursts, allowing the tool to operate rather than applying excessive manual force. When removing rusted or seized fasteners, use penetrating lubricant and start at low impact settings if available. Inspect the socket regularly for wear, cracks or deformation and replace if any damage is detected.

Usage recommendations

Use with appropriate safety equipment, including eye protection and gloves. Match the socket to the correct drive and fastener size before use. Avoid using cheater bars or non-impact hand tools with this impact socket, and store in a dry environment to minimise corrosion.
