Application
Seizing preventionSpace-saving/lightweight
FPD production equipment / Semiconductor manufacturing equipment / Equipment and device structures / General industrial machines / Medical equipment / Food machinery
Characteristics
- High intensity stainless steel hex socket head cap screws.
- Tensile strength 1000 N/mm2, 0.2% proof load 800 N/mm2
- The proof load is approximately 1.8 times that of general stainless steel hex socket head cap screws. Therefore, smaller screw diameters and reduced quantities are available to save space and reduce weight.
- Galling and seizing are prevented by curing the screw surface.
- Unlike plating or coating, there is nothing adhering to the surface, eliminating concerns about contamination due to stripping when tightening.
- Suitable for preventing seizing in environments where lubricant cannot be used.
- Complies with JIS B 1176, ISO 4762, and DIN 912. For details on shape and dimensions, please refer to the "Technical Information (JIS B 1176, ISO 4762)".
- For details on the features of the special surface hardened treatment, please refer to the "Advantages of Special Surface Hardened Screws".
Precautions for Use
May have lower corrosion resistance than general SUS316L.We recommend performing a test under the same usage conditions as in actual usage in advance.
