SATA ST09105ASJ 9-Piece Metric Long Ball Point Hex Key Set

The set includes nine metric hex keys that cover a broad range of common fastener sizes. Exact sizes vary to provide broad compatibility for professional and DIY tasks.

The longer reach provides enhanced leverage, making it easier to access fasteners in tight or recessed areas and helping reduce user fatigue during repeated use.

The ball-end allows you to engage fasteners at an angle, enabling off‑axis turning and easier entry in confined spaces where a straight approach isn’t possible.

The keys are crafted from high‑strength steel designed to withstand high torque and repeated use, maintaining shape and performance under demanding tasks.

All nine keys come in a compact storage case that keeps them organized, protected, and easy to carry between job sites.

They’re well-suited for automotive work, machinery assembly and maintenance, and household tasks involving bulky or hard‑to‑reach fasteners, as well as enclosure hardware in equipment racks.

Yes—start with the smallest key that fits, apply steady pressure with controlled torque, use the angled entry to reduce wrist strain, lubricate the fastener if needed, and switch to a shorter tool if you hit a hard stop to avoid rounding.

Consider the total number of sizes, the presence of a ball-end versus straight ends, the overall tool length for reach, the material and durability, and how the storage case fits your workspace or on-site kit.

Yes, the set is designed for high-torque use with its high‑strength steel construction, but as with any hex key, avoid using excessive torque or improvising with tools not designed for this purpose to prevent damage.

You get nine metric hex keys with a long reach and ball-end capability in a durable, portable case, which combines flexibility for hard-to-reach fasteners with long-term durability—helping reduce tool switching and time on the job.
