Stainless Steel (Low Temperature Black Chrome Treatment) Hex Nut - Type 3
This is a stainless steel hex nut with a high corrosion-resistant, matte black "low-temperature black chrome treatment" applied to its surface. It is a type that conforms to JIS supplementary standard category 3 (low-profile double-sided). It can be combined with JIS category 1 or 2 hex nuts and used as a double nut. The non-glossy black surface is ideal for optical devices that require anti-glare properties. It has corrosion resistance that is tens of times greater than black dyeing. The low-temperature black chrome treatment offers excellent wear resistance, light-selective absorption, and heat absorption, leading to increased demand in industries such as semiconductors, liquid crystal, and optical technology-related equipment. It is compliant with EU-RoHS2 standards. Applications: Semiconductor and liquid crystal manufacturing equipment, optical inspection equipment, top covers and diaphragm parts for high-end single-lens reflex digital cameras, precision drive components such as LM guides and gears. Standard film thickness: 3 to 12 μm. Since there is no need to apply oil, it can be used in clean rooms.
