No. 2: Vacuum environments

No. 2: Vacuum environments

Vacuum technology is often used in semiconductor manufacturing equipment. A vacuum is not required for all equipment. A vacuum would mainly be required for equipment that uses plasma or an electron beam. In Part 2, we introduce some NBK products that are ideal for use in these vacuum environments!

Description of Tamper Resistant Screws for the Engineers

This is the page on tamper-resistant screws in "Description of Special Screws for Designers." We introduce here what tamper-resistant screws are, the advantages of their use, various usage examples, and their types and characteristics.

Galling and Seizing

Galling and Seizing

This is a phenomenon that occurs while tightening, where the surface of the screw thread melts or welds due to frictional heat and the screw stops moving. To resolve galling, NBK's special surface treatment screws, such as those with fluorine coating, are recommended.

Micro Screws: M0.6 (S0.6) to M2.6 Lineup

Micro Screws: M0.6 (S0.6) to M2.6 Lineup

NBK offers a wide-ranging lineup of small-diameter screws in various shapes and materials.
Various head diameters and heights are available for the same screw diameters, contributing to saving space.
