Sunex Tools 3504 3/8 in Drive Wobble Extension Set

Designed for automotive repair and DIY projects, the Sunex Tools 3504 3/8 in Drive Wobble Extension Set brings four common SAE extensions together in a compact kit. The standout feature is the 15-degree wobble offset, which lets you reach fasteners tucked behind components without forcing the tool. A steel ball retainer on the male end helps you stay connected during operation, so you can maintain control as you work in tight spaces. Built for longevity, this set is crafted from CR-MO alloy steel to resist bending and withstand high torque from impact tools while maintaining precise fit and function over time.

  • WOBBLE DRIVE provides 15-degree offset in all directions for flexible access
  • STEEL BALL RETAINER on the male end keeps connections engaged during work
  • DUAL SIZE MARKINGS laser etched and roll stamped for quick identification
  • STORAGE TRAY included for organized transport and storage
  • Radius corner design helps distribute torque and reduce wear

Real-world use cases

In cramped engine bays or behind suspensions, the wobble offset makes it easier to orient the tool while maintaining control. The four lengths cover a wide range of fasteners, from panel screws to under-hood hardware, enabling a smoother workflow and fewer contortions.

Durability, quality, and warranty

CR-MO alloy steel delivers long life, while the wobble design and steel ball retainer keep the extensions aligned under load. The set is ANSI-tested for performance and comes with a heavy-duty blow-molded storage case for protection and easy transport. The manufacturer backs the kit with a full guarantee for lasting confidence.
