Irwin 1877499 Impact Drive Socket Adapter 1/4 to 3/8 Inch

Product Description

The IRWIN 1877499 is an impact drive socket adapter designed to convert a 1/4 inch male drive to a 3/8 inch female drive, allowing mechanics and tradespeople to use 3/8 inch drive sockets with 1/4 inch impact drivers and tools. With an overall length of 1 inch, this compact adapter fits into tight spaces without adding unnecessary bulk to the tool assembly. It is built for use with impact-rated tools, making it suitable for fastening applications in HVAC, electrical, plumbing, and general mechanical work where drive size conversion is required on the job.

This adapter is intended for use with 1/4 inch hex shank impact drivers and 1/4 inch drive impact tools when a 3/8 inch drive socket is needed. It is a practical solution for technicians who carry multiple socket sets and need drive compatibility across tools without switching out full socket sets. Typical applications include equipment installation, panel work, and mechanical assembly where impact fastening is preferred.

Key Features

• Converts 1/4 inch male drive to 3/8 inch female drive for cross-drive compatibility
• Impact drive rated for use with pneumatic and cordless impact tools
• Compact 1 inch overall length minimizes extension in confined spaces
• Lightweight at 0.08 pounds for easy carry in a tool pouch or bag

Compatibility

Designed as an OEM-style replacement adapter for use with 1/4 inch drive impact tools requiring 3/8 inch female drive socket compatibility.

Installation Notes

Installation requires no special tools — simply insert the 1/4 inch male end into the impact driver chuck and seat a 3/8 inch drive socket onto the female end. Verify the socket is fully seated and the retaining mechanism is engaged before applying torque. Use only with impact-rated sockets to avoid socket failure under impact loading.
