SDC Clean Bolt with Anti-Seizing Function for Clean Environments

SDC Clean Bolt with Anti-Seizing Function for Clean Environments

With the power of plasma, no lubricant, no impurities! Solving problems of seizure and galling.

In clean rooms that dislike impurities, semiconductor manufacturing equipment, food and beverage-related manufacturing equipment, and cosmetic and pharmaceutical manufacturing equipment and piping joints where cleanliness is required, various surface treatments (such as plating, coating, and lubricants) may not be used as anti-seizing measures during the tightening of bolts/nuts. Conventional stainless steel bolts/nuts can experience seizing issues when tightened, but by applying our unique technology "SDC Plasma Surface Hardening Treatment," we have created the "SDC Clean Bolt Series," which prevents seizing without the use of any lubricants. 【Features】 ○ Does not use impurities such as lubricants or plating ○ Due to the diffusion penetration treatment, there is no concern about peeling off like with lubricants or plating For more details, please contact us or download the catalog.

[Usage Example] Semiconductor Manufacturing Equipment Design Department

[Usage Example] Semiconductor Manufacturing Equipment Design Department

Even when tightened with strong torque, seizing and galling do not occur! Here are examples of using SDC Clean Bolts.

We would like to introduce a case study of the use of "SDC Clean Bolt" in the design department of semiconductor manufacturing equipment. During the assembly of equipment within semiconductor manufacturing devices, cap screws were tightened onto the main body’s taps, but there were instances where the bolts became seized and could not be removed, or the main body was damaged. This product features a gradient hardening layer within the metal due to "SDC Plasma Surface Hardening Treatment," which prevents seizing and galling even when tightened with strong torque. 【Product Information】 ■ Material: SUS316(L), pure titanium, titanium alloy (6AI-4V) ■ Surface Treatment: SDC Plasma Surface Hardening Treatment ■ Shapes: Hex bolts, hex nuts, hex socket bolts (cap screws), hex socket set screws (hollow sets), and other special shapes are also available ■ Features: Prevents galling and seizing while maintaining the corrosion resistance of stainless steel and titanium ■ Specifications: Processed with gas vent holes, precision cleaning, and special packaging for clean rooms *For more details, please download the PDF or feel free to contact us.
