Description

Ingersoll Rand A31H – 3/8″ DXS® standard anvil (hog ring) is a dedicated drive anvil for the DXS® Drive Xchange System™. It is engineered to deliver efficient torque transfer from the impact wrench to the socket while maintaining a compact overall tool length.

The A31H uses a hog ring retention design that keeps sockets securely in place, even in high-vibration applications, while still allowing quick socket changes. As part of the DXS® system, this anvil lets operators switch between different drive sizes and extended anvils without using torque-robbing adapters.

Key features and benefits

• DXS® Drive Xchange System™ compatible: purpose-built anvil for DXS2 size impact wrenches, enabling fast, tool-free anvil changes.
• 3/8″ standard drive: ideal for light and medium-duty fastening where smaller sockets and tighter access are required.
• Hog ring socket retention: secure grip on impact sockets while still allowing quick changes on the job.
• Optimised torque transfer: direct drive connection helps minimise power loss compared to using separate adapters.
• Durable steel construction: manufactured from high-strength alloy steel for long life under repeated impact use.
• Part of a complete DXS® system: can be combined with other DXS® anvils and DXS2 impact sockets for maximum flexibility.

Typical applications

• Automotive repair and maintenance – suspension, steering and general repair work.
• Fleet and tire service – light commercial vehicles, vans and service trucks.
• General industry and maintenance – assembly, disassembly and repair tasks using 3/8″ drive sockets.
• Workshop service tools – where compact size and fast setup are important.

Notes

The A31H is supplied as a single anvil. Matching DXS2 impact wrench, impact sockets and any extended anvils are sold separately. Always verify compatibility with your specific Ingersoll Rand DXS® impact wrench model.
