The Tolsen 20090 13 Pcs Ball Point Long Arm Allen Hex Key Set handles imperial fasteners ranging from 0.05 to 3/8 inch. Industrial-grade CrV steel withstands high torque without snapping during heavy mechanical work. Ball-end tips engage bolts at off-angles in tight assemblies where standard keys fail.
Key Features
- 25° Entry Angle: Ball point tips engage hex sockets from slanted positions. These access bolts where other components obstruct the path.
- CrV Steel Build: Chrome Vanadium alloy reaches a hardness of HRC 52-56. The metal resists deformation under heavy mechanical loads.
- Long Arm Reach: Extended shank length provides high leverage for stuck fasteners. Users generate more torque with less physical effort.
- Blackened Finish: Heat-treated surface layer reduces corrosion from high humidity. This treatment slows down rust formation on the tool surface.
- Plastic Holder: Friction-fit slots organize all 13 pieces by size. Organized storage prevents the 0.05-inch key from disappearing in tool kits.
