Stainless Steel 304 Hex Head Bolt

About Stainless Steel 304 Hex Head Bolt

• Stainless Steel 304 Hex Head Bolts (also commercially classified as 18-8 or A2 stainless steel) are premium, versatile industrial fasteners renowned for their high strength, ease of installation, and superb atmospheric corrosion resistance. Engineered with a standardized six-sided head design, these bolts ensure uniform torque distribution and prevent slippage when tightened with standard spanners or socket wrenches.

   

  Key Features

   

  • Premium Material Composition: Composed of roughly 18% chromium and 8% nickel, offering strong protection against moisture, oxidation, and common industrial chemicals.

   

  • High Mechanical Strength: Features a robust minimal tensile strength of 515 MPa and yield strength of 205 MPa, making it ideal for heavy structural load bearings.

   

  • Thermal Performance: Demonstrates reliable dimensional stability under wide temperature ranges, functioning continuously up to 800C.

   

  • Polished Smooth Finish: Designed with a clean, silver-bright polished surface that resists aesthetic tarnishing while facilitating smooth, rapid threading into matched nuts or tapped holes.
