FAQ
A: The main difference is the length of the long arm (L1). Standard length works for regular applications; long-reach adds length for typical deep holes; extra-long has the longest arm for reaching ultra-deep cavities and extremely narrow spaces — ideal for large machinery, mold interiors, and deep engine work. For example, 10mm size: standard L1=122mm, long-reach=180mm, extra-long=234mm.
A: This extra-long hex key is made of premium chrome vanadium (Cr-V) steel with full hardening and tempering, achieving HRC 54-58 hardness with strong torque. It resists slipping and breaking under normal use, fully meeting industrial-grade heavy-duty requirements.
A: Yes, we do. Popular sets include 9-piece (1.5-10mm), and we also support custom size combinations. Please contact our sales team for details and pricing.
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.
