Material: 45 steel or 40Cr, 35crMoA, 40MnB, 40MnVB alloy steel
Standard: DIN 74361 - 2 (G) - 2008
1. High-Strength Grade 8 Steel Flanged Hex Head Screws: Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. The material meets SAE J429 specifications for quality. Dimensions meet IFI 111 specifications. Grade 8 steel hex head screws are marked with six radial lines. Head height includes the flange. Length is measured from under the flange.
Black-phosphate steel screws are mildly corrosion-resistant in dry environments. Zinc yellow-chromate plated steel screws resist corrosion in wet environments.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration.
2. High-Strength Metric Class 10.9 Steel Flanged Hex Head Screws: Choose these Class 10.9 steel screws for high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Head height includes the flange. Length is measured from under the flange.
Black-phosphate steel screws are mildly corrosion-resistant in dry environments. Zinc yellow-chromate plated steel screws resist corrosion in wet environments.
Screws that meet ISO 898-1 or SAE J1199 comply with specifications and testing requirements for material quality. Screws that meet ASME B18.2.3.9M or DIN 6921 comply with specifications for dimensional standards.
3. JIS High-Strength Steel Flanged Hex Head Screws: Made to Japanese Industrial Standards, these Class 10.9 steel screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. The zinc plating provides corrosion resistance in wet environments. Head height includes the flange. Length is measured from under the flange.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.
Product Specification
Name: Hub screws
Material: 45 steel or 40Cr, 35crMoA, 40MnB, 40MnVB alloy steel
Hub screws are special screws used to fix the outer hub of the car. Because of the uncertainty of car screws, there is no national standard for cars, but the general model is roughly the same as ordinary hexagonal screws, and there are also various models between M12-M42. Compared with ordinary hexagonal screws, hub screws are generally thicker than hexagonal national standard screws of the same specification, generally have fine teeth, and the thread pitch is roughly 1.5 mm and 2.0 mm. The shape is the same as that of hexagonal screws. Equilateral hexagon, but there will be a taper at one end of the screw, and some inside the taper will have a step for placing nylon washers for locking, and some sides have no steps! And some hub screws have a flange on the tapered part, and generally, there is a flange on the outside, there will be a step inside to place the nylon washer, and generally, the hex nut has a tapered shape!Hub bolts, materials are 35#, 45#, 60#, 16Mn, 65 Mn, 40Cr, 20MnTiB, 35CrMo, 42CrMo optional, thread specification M10~M48, 3/8″
~2″, screw length 2 0~1000 (mm)
