FAQ
Q1: What is the main purpose of the 475mm Flex Handle (Breaker Bar)?
A1: The 475mm flex handle provides maximum leverage and torque. It is primarily used to “break loose” extremely tight, frozen, or rusted bolts that a standard ratchet cannot handle, protecting the ratchet mechanism from damage.
Q2: Why does this set include two different extension bars (200mm and 400mm)?
A2: Heavy machinery often has deeply recessed bolts. Providing a 200mm and an extra-long 400mm extension bar gives mechanics the versatility to reach fasteners at varying depths safely and efficiently.
Q3: Can we customize the surface finish of the tools?
A3: Yes! Depending on your market needs, we can manufacture these sockets with a mirror chrome finish, matte finish, or a black phosphated (oxide) finish for OEM orders. Please contact sales for MOQ details.
Q4: Is the packaging strong enough for the 15.10kg weight?
A4: Absolutely. We use heavy-duty, multi-layer corrugated cartons specifically designed for heavy hardware tools to prevent any breakthrough or damage during ocean and inland freight.
