Bolt "SDC Clean Bolt"

Stainless steel bolts with excellent seizure resistance without lubricant.

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) for preventing galling may not be applicable during the tightening of bolts and nuts. Conventional stainless steel bolts and nuts can experience galling when tightened, but by applying our unique technology, "SDC Plasma Surface Hardening Treatment," we have developed the "SDC Clean Bolt Series," which prevents galling without the use of any lubricants. 【Features】 ○ Does not use impurities such as lubricants or plating ○ Due to diffusion penetration treatment, there is no concern about peeling off like lubricants or plating For more details, please contact us or download the catalog.

Stainless steel hex socket bolt (cap bolt) with nylon lock processing.

This is a hexagon socket bolt with a Nylok treatment applied to the threaded part. Nylok creates a strong friction joint on the threaded part due to the elastic rebound force of the special nylon that is adhered to it, providing a permanent locking function against vibrations and impacts. It exhibits exceptional locking effectiveness in areas with frequent repeated use. Nylok is a registered trademark of Nylok LLC. What is Nylok: Nylok is a reliable locking treatment technology that permanently adheres special nylon to the threaded part. The principle of Nylok's locking mechanism is that when the screw is tightened, the elastic rebound force of the adhered special nylon generates a strong friction joint across the entire threaded part on the opposite side of the processed area, demonstrating a permanent locking function against vibrations and impacts. It shows outstanding locking effectiveness in areas with frequent repeated use. This offers advantages not found in locking nuts that deform the threaded part or in products that use adhesive for locking. This product complies with EU-RoHS standards.
