Stainless steel black spacer hexagonal male and female screws different diameters low-temperature black chrome treatment

This is a stainless steel spacer treated with low-temperature black chrome. The matte black surface is ideal for optical devices that require anti-glare properties. With a film thickness of approximately 2μm and no variation in thickness distribution, it has corrosion resistance several tens of times greater than black dyeing. The screw diameters of the male and female threads are different. Low-temperature black chrome treatment offers excellent wear resistance, light-selective absorption, and thermal absorption, leading to increased demand in industries such as semiconductors, liquid crystal, and optical technology-related equipment. Applications include semiconductor and liquid crystal manufacturing equipment, optical inspection equipment, top covers and diaphragm parts for high-end single-lens reflex digital cameras, and precision drive components such as LM guides and gears. Standard film thickness: 5±2μm. Since there is no need to apply oil, it can be used in clean rooms.
