FAQ
A: The main difference is the length of the long arm. Standard-length keys work well for regular applications, while long-reach versions have an extended L1 dimension to reach deep holes, deep cavities, and narrow spaces — such as automotive engine bays, mold interiors, and machinery cavities. Choose long-reach if your work involves deep-hole operations.
A: This long-reach 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 13-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.
