Crescent CDTA1C Socket Adapter 1/4 to 3/8 Inch Drive

Product Description

The CRESCENT CDTA1C is a socket adapter and universal joint combination that converts a 1/4 inch male drive to a 3/8 inch female drive. It is designed for use with hand-operated socket sets and ratchet drives in professional tool kits. The adapter allows technicians to connect 3/8 inch drive sockets to a 1/4 inch drive ratchet, expanding socket set flexibility without carrying redundant tools. Built to ASME B107.10M standards, this adapter meets recognized industry specifications for socket drive tools. It weighs 0.06 pounds and measures 1.7 inches in length, making it a compact addition to any service bag or toolbox.

The CDTA1C is suited for residential and commercial service work where mixed-drive socket sets are common. HVAC technicians, plumbers, electricians, and general maintenance professionals use drive adapters like this when working in tight spaces or switching between socket sizes mid-job. The universal joint function adds articulation, allowing the socket to work at an angle when straight access is not possible. It is packaged and sold individually, making it easy to replace a lost or worn adapter without purchasing a full set.

Installation Notes

This adapter is a hand-tool accessory and does not require power disconnection or system shutdown for use. Ensure the adapter is fully seated in both the drive ratchet and the socket before applying torque to prevent slippage or rounding. Inspect the adapter for wear or cracking before each use, particularly when working with impact-style hand tools. This tool is intended for hand-ratchet use and should not be used with pneumatic or electric impact drivers unless the tool is specifically rated for impact service.
