Sunex 1800 1/4-Inch Drive Impact Universal Joint, Cr-Mo Steel, Radius Corner Design, Manganese Phosphate Finish, Meets ANSI Standards

Availability set by the retailer

The Sunex 1800 is a 1/4-inch drive impact-rated universal joint (swivel joint) that lets any 1/4-drive socket pivot around obstructions and reach fasteners at awkward angles where a straight extension or socket simply won't fit. Forged from premium chrome molybdenum (Cr-Mo) alloy steel—the best choice for strength and durability under high-torque impact use—it features a radius corner design that drives the side of the fastener instead of the corner. This provides increased strength and avoids rounding off rusted or damaged fasteners, extending the life of both the fastener and the joint. The manganese phosphate (black) finish adds corrosion resistance for long service life in shop and jobsite environments, and a built-in ball detent holds the socket securely in place during positioning. A common size used for repairs, this single-piece unit is ruggedly built and rigorously tested to meet ANSI standards, ensuring peak performance and durability.

Choosing Sockets & Sets

6-point or 12-point sockets — which should I use?

6-point sockets grip the flats of a hex fastener for maximum torque and resist rounding, ideal for stubborn or high-torque fasteners. 12-point sockets offer more engagement positions for tight clearance, but apply force closer to the corners and are more likely to round a worn fastener.

Do I need impact-rated sockets?

Use impact sockets (typically chrome molybdenum, black finish) with impact drivers and wrenches; standard chrome sockets can shatter under impact loads. For hand ratchets, chrome sockets are fine and are thinner-walled for tight spaces. Match the socket drive size to your ratchet.
