FAQ:

Q1: What is the primary difference between long and extra-long hex keys?

A: Extra-long hex keys offer significantly extended reach to access fasteners buried deep within machines or engines, while delivering much higher leverage to break loose seized or high-torque bolts with less effort.

Q2: Will these extra-long wrenches bend or twist under high torque?

A: No. Thanks to the Cr-V steel construction and comprehensive induction hardening, our wrenches retain high structural rigidity and elasticity, preventing permanent deformation or head stripping.

Q3: Can we customize our own brand logo and packaging for retail?

A: Absolutely. We provide complete OEM services, including laser logo marking, customized holder colors, and private-label blister card or color box packaging.

Q4: What is the standard MOQ and lead time for mass orders?

A: For standard stock packaging, the MOQ is low and flexible. For custom OEM orders, the MOQ is typically 1,000–2,000 sets with a turnaround time of 20–30 days.
