1000V VDE Socket Bits With Different Size

Premium High-strength Chrome Vanadium Steel Material
The working end is forged from high-quality chrome vanadium steel, with precision quenching and tempering heat treatment. It delivers high hardness, excellent torsion resistance and outstanding wear resistance, avoiding deformation, twisting or cracking under high torque tightening and loosening operations for long service life.
Complete Rich Size Specifications
This set covers a full range of common metric socket sizes, with multiple lengths available including short, medium and extended long versions. It can meet diverse working demands: short bits for narrow compact spaces, long deep-reach bits for deep-set bolts and hidden fasteners, perfectly matching most electrical terminal screws, switch fittings and equipment bolts.
Precision Machined Inner Hexagonal Drive
Accurately machined inner hexagonal drive fits standard 1/4″ quick-change screwdriver handles, ratchet spanners and electric screwdriver tools tightly without slipping. The precise socket inner profile ensures full contact with bolt heads to prevent edge rounding, protecting fasteners from damage during high-torque operations.
Anti-slip Insulation Surface & Stable Structure
The outer red insulating sleeve adopts a textured anti-slip design, which stays firmly in place without peeling or falling off during frequent use. The integrated insulation structure avoids gaps between the metal core and insulating layer, eliminating hidden risks of electric breakdown and ensuring long-term stable insulation performance.

Perfect for home circuit renovation, socket, switch, lamp and water heater installation, as well as household appliance disassembly and wiring maintenance. The complete range of sizes covers most standard electrical fasteners, allowing safe operation near household power circuits.
Widely used in factory automation equipment assembly, PLC control cabinet wiring, instrumentation installation and mechanical equipment electrical overhaul. The short and extended-length insulated bits can adapt to narrow installation gaps and deep hidden bolt positions inside equipment, meeting high-standard safety requirements for industrial electrical construction.
