Product Introduction
The Ball End Hex Key Set (Long Arm Series) is manufactured from high-quality Cr-V steel with full heat treatment for exceptional hardness and torque resistance. Each wrench features a ball-shaped tip that allows screws to be turned at a 25° angle, making it ideal for tight or obstructed spaces where a straight key cannot operate.
The special chamfer at the tail end ensures smooth insertion, high precision fit, and reduced risk of slipping or stripping screws. The long-arm design (L1) provides greater leverage, while the shorter arm (L2) allows access in narrow gaps. This combination delivers reliable performance without breakage, suitable for machinery repair, automotive maintenance, furniture assembly, bicycle repair, and industrial equipment service.
Available in sizes from 1.5 mm to 22 mm, this set covers the most commonly used metric hex specifications for professional and DIY applications.
