M8 M10 M20 Coarse Thread Metal Bolts with Nuts Fully threaded stud bolt DIN931
Product Description:
DIN 933
Description: DIN 933 specifies fully threaded hexagon head bolts. These bolts have threads that extend along the entire length of the shank.
Applications: DIN 933 bolts are suitable for applications where the entire length of the bolt needs to be threaded. They are commonly used in mechanical engineering, steel construction, automotive manufacturing, and renewable energy projects.
DIN 931
Description: DIN 931 defines partially threaded hexagon head bolts. These bolts have a portion of the shank that is smooth and unthreaded.
Applications: DIN 931 bolts are ideal for structural applications where shear strength and alignment are critical. They are often used in heavy machinery, construction projects, and long-span joints.

Applications:
Black Oxide Hex Bolts: Applications and Advantages
Applications:
Automotive Industry: Widely used in engine components, chassis assemblies, and interior fittings due to corrosion resistance and reduced light reflection.
Machinery & Equipment: Ideal for industrial machinery, agricultural tools, and hydraulic systems where durability and minimal maintenance are critical.
Construction: Employed in structural connections, HVAC systems, and outdoor installations for enhanced weather resistance.
Electronics & Appliances: Used in casings and internal components to prevent rust while maintaining electrical conductivity.
Aerospace & Defense: Applied in non-critical structural parts requiring lightweight corrosion protection.
Advantages:
Corrosion Resistance: The black oxide coating forms a protective layer against moisture and oxidation.
Aesthetic Appeal: Provides a uniform, matte-black finish for a professional appearance.
Minimal Dimensional Change: Unlike coatings like galvanization, black oxide does not alter bolt dimensions, ensuring precise fitment.
Cost-Effective: Lower processing costs compared to electroplating or painting.
Reduced Friction: The smooth surface slightly lowers thread friction during assembly.
No Hydrogen Embrittlement: Unlike electroplating, the process avoids hydrogen uptake, preserving bolt strength.
Compatibility: Works well with secondary coatings (e.g., wax or oil) for added protection.
Technical Notes:
Process: Black oxide (Fe₃O₄) is formed via a chemical reaction with alkaline solutions at high temperatures.
Standards: Often complies with ASTM D769 or MIL-DTL-13924 specifications.
