Socket head screw SNSS-BK

hex socketstainless steelcorrosion-resistant

SNSS-BK is a Hex Socket Head Cap Screws in Super Black surface treatment. The stainless black surface treatment develops a passive membrane on the stainless steel surface up to 200 times of normal to produce a deep black finish. Excellent corrosion resistance. 8 times more resistant compared to SUS316L and 32 times to SUS304, respectively. The membrane contains no impurities and has extremely low outgas even in vacuum environments. Spectral reflectance is 1.5% or less. For optical instruments and other applications that require antireflection. Deep black color decorates surfaces of equipment and devices. Application Antireflection. Optical instruments, FPD production equipment, semiconductor devices, vacuum applications, and general industrial machines Related Service Cleanroom Wash & Packaging Service(Screw) Please feel free to contact us for a quotation.
