Using precise torque is critical for securing parts without overstraining the threads or leaving dangerous looseness. Torque wrenches allow mechanics and engineers to apply optimal torque quickly and consistently.How Torque Wrenches WorkTorque wrenches have a ratcheting head calibrated to the desired torque value. As the wrench is pulled, internal springs compress. Upon reaching the preset level, the wrench head slips and emits an audible "click" to signal target torque is achieved. This prevents overtightening. Locking collars allow securing the torque setting. Most wrenches have exchangeable drive sizes like 3/8" or 1/2" to match various bolt and socket heads.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
