Featuring a gear mechanism that only allows motion in one direction, the ratchet allows the user to swing the handle back and forth to gradually tighten or loosen whatever is engaged with the socket or attachment.Ratchets come in a wide variety of sizes, drive sizes, handle lengths, and configurations to suit various applications. A typical ratchet consists of a cylindrical head with the gearing mechanism inside and a lever handle protruding out to allow the user to apply torque. The head has a square drive lug on the end that accepts different-sized detachable sockets, extensions, adapters, and bits. Common drive sizes are 1/4", 3/8", and 1/2", indicating the size of the square lug and sockets used.The key component that gives the ratchet its function is the reversible gearing mechanism inside the head. It allows continuous rotary motion in one direction while slipping in the opposite direction when the handle is reversed. This allows the user to quickly swing the handle back and forth while the socket turns incrementally in the set direction. A switch, button, or lever on the head is used to reverse the gearing and the direction of rotation.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<0.50-0.30-0.50<0.300.30-0.60One of seven types of shock-resisting steels under the AISI ClassificationHigh strengthHigh toughnessWear resistanceHigh hardnessResistance to shock loading45#0.42-0.050.17-0.37-≤0.250.50-0.80≤0.25-Compared with A3, it has higher strength and resistance to deformation.A30.95-1.050.10-0.500.15-0.504.75-5.500.40-1.00-0.90-1.40High-quality high carbon alloy tool steelProduct Application Company ProfileQuality ControlCertificationsFAQ
