In pursuit of our motto, “Idea development to make society safer and more secure with fasteners that do not loosen,” we strive for quality control that ensures safety from product development through production and sales. We also take product feedback about customer issues very seriously, and work to improve our process from product development to product inspection and mass production.

Production and shipping quality control
This gauge measures surface shape to high precision. The probe tip traces the surface while measuring protrusions and depressions. The detector can be switched to enable shape and surface roughness measurement.
This is a non-contact dimension measurement apparatus. Taking batch measurements within a certain range, the apparatus quickly makes a pass-fail determination based on geometric tolerances.
This is a high-power microscope. It has an XY stage, automatic focus, image processing, dimension measurement capability, and a 3D composition feature. It observes fastener shape and the surface state to quickly solve problems.
Mitutoyo QM-Data 300
This device precisely measures 3D coordinates. When the probe tip comes into contact with the surface, the probe position is taken as three-dimensional coordinate data, and calculations are performed based on multiple coordinate values and information about planes, cylinders, cones and other geometric shapes.
This is a hardness tester. It measures the Rockwell hardness of materials.
