Key Functions
30-Degree Working Angle
The joint rotates smoothly and continuously at up to a 30-degree angle, letting you drive 11 mm fasteners that sit off-axis behind brackets, manifolds, and frame members.
Stronger 6-Sided Pinless Joint
The solid ball-and-socket joint is stronger than pin-style joints, and the 6-sided ball operates more smoothly than 4-lug designs—durability that protects your $10.00 purchase through heavy impact use.
Works with Both Anvil Types
Smooth walls support friction ring engagement, and a detent pin hole lets you choose pin retention when needed.
Compatibility and Use Cases
Fits all 3/8 in. drive impact wrenches, ratchets, and breaker bars. Ideal for automotive engine bay, exhaust, and chassis fasteners in tight angled positions.
How It Compares
Straight sockets fail on angled fasteners; separate universal joints plus sockets add cost and wobble. This integrated universal joint socket is the affordable alternative—one tool, one price. Against pin-joint competitors, TEKTON's solid ball-and-socket design is stronger and smoother.
