Socket 12-point 3/4" 38 mm Honiton H2638

The Honiton Socket 12-point 3/4" 38 mm (model H2638) is a heavy-duty hand tool component designed to fit 3/4" drive tools and engage 12-point fasteners. It combines a 38 mm contact diameter with a 12-point internal profile to allow multiple engagement angles, making it easier to access bolts in confined spaces while reducing the risk of rounding fastener corners. The socket is intended for use in automotive repair, industrial maintenance and other heavy-duty mechanical tasks requiring a robust connection between drive tool and fastener.

Advantages

The 12-point geometry permits finer indexing on hexagonal and 12-point fasteners, enabling operations where clearance is limited. The 3/4" drive size provides compatibility with common torque wrenches, impact ratchets and breaker bars used for high-torque fastening and loosening. The 38 mm size addresses medium to large fasteners commonly found on commercial vehicles and industrial equipment. The socket’s design helps distribute load across more contact surfaces, which reduces the likelihood of fastener damage under high torque.

Suitable for

• Automotive heavy-duty repairs (wheel nuts, suspension and drivetrain components)
• Industrial maintenance and equipment servicing
• Construction machinery and agricultural equipment maintenance
• Use with 3/4" torque wrenches, impact wrenches and breaker bars

Key specifications

• Drive size: 3/4" compatible
• Socket profile: 12-point internal
• Nominal size: 38 mm
• Intended use: high-torque fastening and loosening
• Typical applications: automotive, industrial and heavy-duty repair

How to use

Select a compatible 3/4" drive tool such as a torque wrench, ratchet or breaker bar. Ensure the socket is free of debris and that the fastener seating surface is clean. Push the socket fully onto the drive square until it clicks or seats securely, then place the socket over the fastener and apply torque in the required direction. For impact tool use, verify the socket material and rating are suitable for impact operations before use. After use, inspect the socket for wear, cracks or distortion and store it in a dry toolset or case.

Usage recommendations

Use the socket with tools rated for the expected torque and avoid excessive force beyond tool or fastener specifications. For repetitive high-torque or impact applications, confirm the socket material and heat treatment are appropriate for impact use. Regularly inspect contact surfaces for rounding or wear and replace the socket if damage is observed to maintain safe and effective operation.
