Milwaukee Electric Tool Corp 48-32-5731 Socket Adapter

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 48-32-5731 is a SHOCKWAVE 1/4 inch hex to 3/8 inch square socket adapter designed for use with impact drivers and drill drivers. It converts a standard 1/4 inch hex shank tool interface to a 3/8 inch square drive, allowing tradespeople to run 3/8 inch drive sockets directly from an impact driver. This package contains 10 individual adapters, making it a practical stock item for tool kits, service vans, and job-site supply. The adapter is built to handle the rotational shock loads typical of impact driving applications.

This adapter is suited for electrical, mechanical, HVAC, and plumbing tradespeople who use impact drivers as a primary tool and need to drive fasteners with socket sets. It is commonly used in panel work, equipment installation, and mechanical assembly where switching between a dedicated socket wrench and an impact driver is impractical. The 10-unit pack supports fleet stocking and reduces downtime when adapters are misplaced on busy job sites.

Key Features

• Converts 1/4 inch hex shank to 3/8 inch square drive for impact driver compatibility
• SHOCKWAVE design rated for impact driver torque and shock loads
• Pack of 10 units for job-site and fleet stocking
• Compact form factor adds minimal length to the tool stack
• Compatible with standard 3/8 inch drive socket sets used across trades

Compatibility

Designed for use with any impact driver or drill driver accepting a 1/4 inch hex shank, and compatible with standard 3/8 inch square drive socket sets.

Installation Notes

Installation requires no tools — insert the 1/4 inch hex end into the tool's bit holder until it seats and locks. Ensure the 3/8 inch square drive end fully engages the socket before applying torque. Inspect the adapter for wear or deformation periodically, as impact-driven adapters are subject to repeated shock loading. Replace any adapter showing visible cracking or rounding of the drive interface.
