⚡ At a Glance

  • Best for: DIYers and mechanics needing access to awkward, hard-to-reach fasteners

Reach Screws in Narrow Spots – With 300mm flexible shafts

Long, flexible shafts bend to navigate around obstructions while the 1/4 inch hex shank accepts standard bits. High carbon steel gives the shafts strength so torque transfers through bends rather than collapsing.

Access fasteners behind dashboards, inside computer cases and between furniture joints without dismantling surrounding panels, saving time and reducing effort.

Built for Repeated Use – Thanks to high carbon steel construction

High carbon steel construction resists wear and retains shape under load better than softer metals. Metal flexible extensions provide a firmer feel for tougher tasks while the softer holder protects screw heads when needed.

Durable materials cope with routine automotive and household repairs, so the set remains reliable across multiple projects.

Works with Common Toolheads – With a 1/4 inch hexagon shank

Standard 1/4 inch hex shank fits most hand drills, electric screwdrivers, cordless drivers and pneumatic screwdrivers. Compatibility includes low-speed DC hand drills and typical bit holders.

Switch between manual and powered tools without additional adapters, making the kit useful for both light DIY and workshop tasks.
