DIN 74361 High Strength Wheel Hub Bolts Forged Extended Flange Screws for Automotive Fastening

These wheel hub bolts are used to connect wheels, hubs, flanges, and related automotive fastening positions where stable clamping force and reliable thread engagement are required. The bolt body can be made from steel, stainless steel, carbon steel, 40Cr, or 35CrMo according to the required grade, application environment, and buyer specification.

For automotive and heavy-duty fastening, material and grade selection is very important. Carbon steel is suitable for general industrial and vehicle fastening requirements. 40Cr and 35CrMo are commonly selected for higher strength fastener applications where improved mechanical performance, toughness, and load-bearing capability are needed.

Surface Treatment Options

Zinc plated finish provides a clean metallic appearance and practical corrosion protection for storage, transportation, and general automotive fastening. It is suitable for wheel bolts, hub bolts, flange bolts, machinery bolts, and replacement fasteners used in normal environments.

Plain finish is suitable when the bolt will be used in controlled conditions, receive later surface processing, or be supplied according to a buyer’s own treatment process. It is also suitable for orders where dimensional matching and mechanical performance are prioritized over decorative appearance.

Black finish gives the bolt a darker surface and is often selected for automotive parts, machinery components, repair parts, and assemblies where a black appearance is required. It is also useful for fastener distributors who need different finish options for separate market channels.

Hot dip galvanized finish, also listed as HDG, can be selected for applications requiring stronger corrosion resistance. For wheel hub bolts and precision automotive fastening, coating thickness, thread fit, and mating nut compatibility should be matched according to the final drawing and assembly requirement.

Application

These high strength wheel hub bolts are suitable for automotive wheel assemblies, hub fastening, truck wheel repair, trailer components, agricultural vehicle parts, machinery maintenance, flange connections, equipment assembly, and customized non-standard fastening systems. Grade 4.8 and 6.8 options are suitable for general fastening and lighter-duty assembly.

Grade 8.8 can be used for stronger mechanical connections and industrial fastening. Grade 10.9 and 12.9 are suitable for high tensile fastening positions where the mating parts, installation torque, and working load require higher strength bolts.

For buyers in the automotive parts, repair, distribution, and machinery industries, this product is useful for both regular stock supply and project-based customization. The wide M2-M100 size range and 10-300mm length range make it suitable for standard wheel bolt replacement, customized flange bolt production, and OEM fastener development.
