9-Piece CrMo Torx Key Set

Teng Tools delivers a professional-grade 9-piece TX key collection built from CrMo steel and housed in a compact folding holder. The set includes sizes TX8, TX9, TX10, TX15, TX20, TX25, TX27, TX30, and TX40 — covering the Torx fasteners tradesmen encounter most frequently across automotive, industrial, bicycle, and general maintenance work.

Each L-shaped key provides two working ends. The short arm delivers higher torque for stubborn fasteners, while the long arm extends your reach into recessed or hard-to-access locations. The specially shaped tips on the long arm let you engage fasteners at an offset angle, which is critical when surrounding components block a straight approach.

CrMo steel gives these keys a meaningful advantage in toughness and fatigue life. Where lesser alloys can twist or round under heavy use, chrome molybdenum maintains its profile and keeps delivering positive fastener engagement job after job.

The red and black folding holder weighs just 175 g with all nine keys installed. It keeps every size organized and instantly identifiable, and it folds flat enough to slide into a pocket or tool pouch. When you need a single size, flip it out, do the work, and fold it back — no hunting through a drawer full of loose L-keys.

Whether you are working under a dashboard, inside an engine bay, or adjusting bicycle components on the trail, this set puts the right Torx size in your hand without the bulk of a full driver kit.
