Product Overview
This ball end long-reach hex key wrench is precision-crafted from premium chrome vanadium (Cr-V) steel, fully hardened and tempered for high hardness, superior strength, and excellent toughness — ensuring no slipping or breaking during use. The ball end design enables 25° angled operation, allowing hex screws to be turned from the side in tight spaces or when screws are partially obstructed, greatly increasing operational flexibility. The extended L-arm reaches deep holes and cavities. The other end is a flat head with chamfered tip for quick alignment and insertion. The electroplated surface provides excellent corrosion resistance and a clean, polished appearance. Widely used in automotive repair, machinery assembly, furniture installation, bicycle maintenance, and various tight-space applications.

FAQ
A: Ball end keys enable 25° angled operation, allowing screws to be turned from the side — ideal for tight spaces and obstructed screw access. Flat head keys provide full contact with the screw, delivering maximum torque without damaging screw edges, better for high-torque applications. This model features both ball end and flat head, giving you two functions in one wrench.
A: When the ball end is aligned straight (0° angle), torque is essentially the same as a flat head. Torque decreases as the angle increases. For high-torque work, use the flat head end with straight alignment. The ball end is ideal for medium-to-low torque tasks where angled access is needed. This model uses fully hardened Cr-V steel for excellent overall strength and torque performance.
A: The long-reach version has longer L1 (long arm) and L2 (short arm) than standard length. For example, 10mm size: standard L1=122mm, long-reach L1=180mm. The long-reach version can reach deeper holes and cavities, suitable for deep-hole and deep-cavity applications.
A: Yes, we provide OEM/ODM services including laser logo, color box packaging, and blister card packaging. The MOQ for standard individual items is 1,000 pieces, and 500 sets for wrench sets. Contact our sales team for specifics.
A: Standard in-stock sizes ship within 1-3 business days. Custom orders typically take 15-30 days depending on quantity and specifications. We offer sea freight, air freight, and international express, with trade terms including FOB, CIF, and DDP.
