Milwaukee 49-66-6733 1 Inch Drive Socket Universal Joint

Product Description

The MILWAUKEE 49-66-6733 is a 1-inch drive socket universal joint engineered for high-torque impact applications. Built from forged impact steel, it delivers the torsional strength needed to handle heavy-duty fastening work without failure. A 25-degree swivel range provides access in tight or obstructed spaces where a straight drive cannot reach. Laser-etched size markings and a laser-etched part number make identification fast, even in low-light job-site conditions. The pin-less construction reduces a common failure point found in traditional universal joint designs. Licensed trade professionals and industrial mechanics reach for this joint when working with 1-inch drive impact wrenches on demanding fastening tasks.

This universal joint is suited for use in industrial, commercial, and heavy mechanical service environments where 1-inch drive impact wrenches are standard. Its dual-hole design and ring groove allow for straightforward attachment and removal of impact sockets without fumbling or downtime. The ball detent mechanism retains impact sockets securely during use, reducing the risk of dropped sockets in overhead or confined work areas. Applications include heavy equipment maintenance, fleet service, structural steel work, and other trades that rely on 1-inch drive tooling for high-torque fastening.

Compatibility

Designed for use with 1-inch drive impact wrenches and impact sockets. Compatible with impact socket sets requiring a 1-inch drive universal joint connection.

Installation Notes

Installation and removal of this universal joint should be performed with the impact wrench powered down and any pneumatic or hydraulic supply disconnected. Inspect the joint and mating sockets for wear or damage before each use in high-torque service. This is a hand-tool accessory; no special installation tools or electrical lockout procedures are required, but standard job-site PPE practices apply.
