Small Diameter 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.

What are low profile screws? Find advantages, disadvantages, and usage examples explained here!

Here we introduce advantages, usage examples, lineups and the like regarding screws with lower head height than ordinary screws, referred to as "low profile screws" or "low profile cap screws" (low head, slim head).

All you need to know about the roles and types of washers!

This page introduces washers. As well as a description of washers, the washer products handled by NBK are introduced.

No. ９: Increasing Throughput

Here we introduce products that help improve conveying speed and downsize equipment in order to increase throughput.
