Reaching fasteners buried deep inside engine bays or confined mechanical assemblies can be frustrating without the right tools. The WNB WB10045 9 Piece Wobble Extension Bar Set is designed to solve that problem, giving mechanics, technicians, and serious DIY users the flexibility to work efficiently in restricted spaces.
This comprehensive set includes three drive sizes — 1/4 inch, 3/8 inch, and 1/2 inch — each supplied in three practical lengths ranging from 50mm to 250mm. Whether you are removing deeply recessed bolts, accessing awkward suspension fixings, or working around engine components, this kit provides the reach and angle adjustment required.
Manufactured from high-quality drop forged and heat-treated chrome vanadium steel, these extension bars are built for strength and durability under demanding workshop conditions. The nickel and chrome plated finish enhances corrosion resistance, protecting the tools from rust and chemical exposure common in automotive environments.
Dual Function Wobble Design
Each extension can be used in two ways:
-
Fully inserted for standard straight extension use
-
Partially inserted to activate the wobble function
The specially machined convex drive allows up to approximately 15 degrees of flex, enabling sockets to access bolts at slight angles without the need for universal joints. This makes them ideal for deep, narrow engine bays and confined mechanical assemblies.
Knurled grip sections provide improved manual control when spinning fasteners by hand, even when wearing gloves or working with oily components.
The tools are clearly labelled and organised in a precision-cut EVA foam tray, making them suitable for professional tool chests and workshop drawers.
