FAQ
Q1: What voltage can these insulated sockets withstand? What is their insulation rating?
A: Our insulated sockets feature special insulation treatment and are suitable for most low and medium voltage live working scenarios when used as part of a complete insulated tool chain. The specific voltage rating depends on the accompanying insulated tools and operating environment. We recommend verifying against your actual working voltage before use and strictly following relevant safety operating procedures.
Q2: What’s the difference between the 10mm and 12.5mm drive series? How do I choose?
A: The 10mm (3/8″) drive series has a smaller drive tang, suitable for small to medium bolt sizes ranging from 8mm to 22mm. The 12.5mm (1/2″) drive series has a larger drive tang that can handle greater torque, suitable for larger bolt sizes from 10mm to 32mm. Choose based on your existing insulated ratchet wrench drive size and the bolt sizes you commonly work with.
Q3: How are these different from regular sockets?
A: The main difference is insulation performance. Standard sockets have no insulation protection and cannot be used for live electrical work. Our insulated sockets undergo special insulation treatment and form a complete insulating protection chain when paired with insulated wrenches and extensions, effectively preventing electric shock — ideal for electricians and power maintenance near-live work scenarios. We also use Cr-V steel forging for superior strength and durability compared to ordinary carbon steel sockets.
Q4: Can the sockets be used alone, or do they require insulated wrenches?
A: Insulated sockets must be used with insulated ratchet wrenches, insulated extensions and other insulated tools to form a complete insulation protection chain. Using the socket alone cannot provide adequate insulation protection. For best safety results, we recommend pairing them with our same-series insulated tools.
