They allow standard driver bits to be used like a traditional socket wrench. Bit sockets have a hollow, cylindrical shape with a hole in the side or top to insert bits.The hex-shaped exterior of bit sockets fits standard ratchets, extensions, and power drills. This enables excellent torque and convenience for driving screws. Meanwhile, the interior bit grips and turns the fastener. Common bit types used include Phillips, slotted, Torx, square, and hex.Uses:Automotive repair - Handy for removing screws on panels, brackets, trim, and other components. Allows reaching into tight spaces.Machinery maintenance - Useful for removing casing and motor screws during equipment service and repair. Provides speed and torque.Construction and assembly - Quick driving and sinking of self-tapping screws into metal and wood. The deep socket helps prevent cam out.Home DIY projects - Allows easy driving of various screw types for building furniture, installing fixtures, cabinets, and other tasks.Most bit sockets have magnets integrated into their design to hold bits securely and prevent dropping. This helps keep the bit aligned when in awkward positions. Quality bit sockets are made of rugged chrome-vanadium steel for strength and durability.For versatility in driving different screw types, a set of bit sockets paired with screwdriver bits is essential. The combination offers portability, access in tight spaces, and added driving force. Bit sockets are a useful addition to any toolbox.Main Fastener CoatingTypesApplicationSpray Test HoursCharacteristicsMirror Nickel-platingALL Metal72HoursStableExcellent polishing performanceImprove Wear resistanceWide range of applicationsMatt Nickel-platingALL Metal72HoursBlack Nickel-platingALL Metal48HoursHigh absorption rate of solar energyUsed in solar collector panels.Manganese PhosphateALL Metal72HoursEnhanced resistanceSand BlastALL Metal-Remove paint, rust, and residue scratches or casting marksElectrophoresisALL Metal1000HoursMaintain metallic lusterAnti-corrosion propertiesColor ElectroplatingALL Metal96HoursImprove mental strength Prevent metal oxidation  Steel Material  Chemical CompositionTypesCSiVCrMnNiMoCharacteristicCR-MO0.18-0.230.15-0.35-0.40-0.600.90-1.20-0.13-0.2041xx-series SAE steel gradesExcellent strength-to-weight ratioStronger and harderNot easily weldedCRV0.50.30.180.80-1.100.70-0.90--6000-series SAE steel gradesSuitable for hardeningResist abrasion, oxidation, and corrosionImprove material elasticityS20.40-0.550.90-1.20
