The hexagonal shank with ball end allows smooth tightening and loosening at angles up to 25°, making it ideal for maintenance, assembly, automotive, workshop, and DIY tasks where straight access isn’t possible.

Made from high-quality S2 steel for outstanding strength and resilience, each key is heat-treated to a 58–62 HRC hardness for long service life and reliable torque transfer. The satin finish combined with a plastic-coated, color-coded design improves grip, comfort, and quick size identification.
The set is supplied in a practical plastic hanger that keeps all 9 keys organized and easy to carry—perfect for toolboxes, service bags, and on-site work.
