Product DescriptionPRODUCT PARAMETERWheel Hug BoltWheel bolts are high-strength fasteners securing wheels to vehicle hubs, designed to withstand radial/axial loads, torque, and vibration. Made of 10.9/12.9 grade alloy steel (zinc-plated or Dacromet-coated for corrosion resistance), they feature tapered/spherical seats to align with wheel hubs, ensuring tight, centered fits. Standards like DIN 79063, ISO 8665 specify sizes (M12–M14 common) and thread pitches (1.25/1.5mm) for cars/trucks.Applications:Automotive: Attach wheels to passenger cars, SUVs, and light trucks (critical for safe acceleration/braking).Commercial Vehicles: Secure heavy-duty wheels on trucks, buses, or trailers (high-tensile variants handle heavy loads).Motorcycles: Fasten wheels to frames, with smaller sizes (M8–M10) for lighter loads.Racing: Use high-performance alloys for enhanced torque resistance during high-speed maneuvers.Proper torque (per manufacturer specs) is vital—prevents loosening or hub/wheel damage.nominal sizeM12M8M103.753.75d×75×90Pthread pitch1.51.251.51515dkHead outer diameterMax1913167590Min1812.7315.73120100d2tooth outerMax13.0556Min12.94.75.7L1Tooth widthMax7.52.312.81Min72.062.56zTeeth4122.4dwDiameter of the supporting surfaceMin17.5d1head diameterMax15.2Min14.8h2Clearance Gap WidthMax1.5Min0.5dsRod diameterMax12Min11.93hHead HeightMax4.5Min4.2h1Platen thicknessMax3.5Min2.5Lgclamping lengthMax17Min14rMax0.7Min0.4LsMax13.25Min12.75tAddendum WidthMax0.5daDiameter of the transition circleMax14ABOUT USLONGSHI FASTENERS MANUFACTURING CO.,LTD.,Longshi Fastener Manufacturing Co., Ltd., founded in 2008, is located in Shahe City, Hebei Province, close to the country's largestLarge fastener industrial cluster - Yongnian standard parts Industrial Park.
