Milwaukee 48-32-5031 1/4 Hex to 3/8 Drive Socket Adapter

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 48-32-5031 is a Shockwave 1/4 inch hex shank to 3/8 inch drive socket adapter designed for impact fastening applications. Measuring 1-7/8 inches in length, it converts a standard 1/4 inch hex power tool output to accept 3/8 inch drive sockets. The adapter is manufactured using a proprietary steel heat treat process engineered for maximum strength and durability under the repeated shock loads generated by impact drivers. This is a single-unit accessory sold in packages of six, suited to electricians, plumbers, HVAC technicians, and general contractors who run 1/4 inch hex impact drivers and need 3/8 inch socket compatibility on the job.

The 48-32-5031 is appropriate for residential and commercial fastening work where a 1/4 inch hex shank impact driver must drive larger 3/8 inch drive sockets. Typical use cases include structural fastening, mechanical assembly, and service work across trades. The compact 1-7/8 inch overall length keeps the tool profile short in confined spaces, making it practical for panel work, equipment installation, and tight mechanical bays.

Key Features

• Converts 1/4 inch hex shank impact driver output to 3/8 inch square drive socket fitment
• 1-7/8 inch overall length for use in confined spaces
• Proprietary steel heat treat process for strength and durability under impact loads
• Designed specifically for impact fastening applications, not hand-tool use only
• Sold in a package of six units for stocking service vehicles or toolboxes

Compatibility

Designed as an OEM-style accessory for use with 1/4 inch hex shank impact drivers accepting standard hex shank bits, paired with any 3/8 inch square drive socket.

Installation Notes

Installation requires no tools — insert the 1/4 inch hex shank into the impact driver chuck and seat fully before applying load. Ensure the 3/8 inch drive socket is fully engaged on the square drive before operating the impact driver. Inspect the adapter for wear or deformation periodically, as impact cycling can fatigue any adapter over time. Remove from the driver before storing loose in a toolbox to prevent chuck wear.
