Product Description
Our insulated hex bit sockets are forged from premium Cr-V steel with precision heat treatment, delivering exceptional hardness, high torque capacity and long-lasting durability. The fully insulated sockets form a complete insulation protection chain when used with insulated ratchet wrenches, effectively preventing electric shock hazards. Available in 10mm (3/8″) and 12.5mm (1/2″) drive series with hex sizes from 4mm to 10mm and working lengths of 75mm and 120mm, they are ideal for hex bolt assembly and disassembly in power maintenance, electrical installation and industrial repair — essential accessories for electrician insulated tool kits.
Product Features
- Cr-V Steel Forging: Forged from high-quality chrome vanadium steel with through-hardening and tempering, offering superior strength, excellent toughness, strong impact resistance and much longer service life than ordinary carbon steel tools
- Full Insulation Protection: Special insulation treatment throughout the socket creates a complete insulating chain when paired with insulated ratchet wrenches, effectively preventing electric shock and ensuring operator safety
- Two Drive Series: Available in 10mm (3/8″) and 12.5mm (1/2″) drive sizes, compatible with different insulated ratchet wrenches and extension bars
- Wide Size Range: 4 sizes from 4mm to 8mm in the 10mm series, and 5 sizes from 4mm to 10mm in the 12.5mm series — meeting most hex bolt assembly and disassembly needs
- Two Working Lengths: 75mm length for the 10mm series and 120mm length for the 12.5mm series, adapting to different depth requirements — the shorter version offers flexibility while the longer version provides extended reach
- Precision Hex Bit: Precision-machined hex bit tip fits tightly with hex socket screws, reducing slipping and effectively protecting bolt inner holes from wear
- Anti-Corrosion Surface: Treated with anti-rust surface coating for excellent corrosion resistance, suitable for damp, dusty and other harsh working environments
- Standard Drive Interface: Standard-sized drive tangs are compatible and interchangeable with mainstream brands of insulated ratchets and extensions

FAQ
Q1: What’s the difference between insulated bit sockets and regular bit sockets?
A: The main difference is insulation performance. Standard bit sockets have no insulation protection and cannot be used for live electrical work. Our insulated hex bit sockets undergo full-body insulation treatment and form a complete insulating protection chain when paired with insulated ratchet 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 tools.
Q2: How do I read the size? What does 4×75mm mean?
A: The first number indicates the hex bit width across flats (in mm), and the second number indicates the total working length of the bit socket (in mm). For example, 4×75mm means a 4mm hex bit tip with a 75mm total length. Choose the bit size based on the hex socket screws you need to work with.
Q3: What’s the difference between 10mm and 12.5mm drive series? How do I choose?
A: The 10mm (3/8″) drive series with 75mm working length covers sizes 4-8mm, suitable for small to medium hex bolts and offering flexible operation. The 12.5mm (1/2″) drive series with 120mm working length covers sizes 4-10mm, handles greater torque, and is better for larger hex bolts and deeper access applications. Choose based on your existing insulated ratchet wrench drive size and the bolt sizes you commonly work with.
Q4: Do these only come with hex bits? Do you have Phillips, slotted or other bit types?
A: This series focuses on hex bit sockets, which are the most commonly used. If you need insulated bit sockets with Phillips, slotted, Torx or other bit types, please contact our sales team to discuss custom options or explore our other product series.
Q5: Can these bit sockets be used alone, or do they require insulated wrenches?
A: Insulated bit sockets must be used with insulated ratchet wrenches, insulated extensions and other insulated tools to form a complete insulation protection chain. Using them alone cannot provide adequate insulation protection. For best safety results, we recommend pairing them with our same-series insulated tools.
Q6: Do you offer OEM branding? Can you create custom bit socket sets?
A: Yes, we offer OEM services with custom brand logos on products and packaging. We also support custom bit socket set combinations based on customer requirements — you can specify the size combination and packaging style. Please contact our foreign trade team for detailed information.
