[Technical Column] The Risks of Foreign Matter Contamination in Food Manufacturing Lines and Their Countermeasures

[Technical Column] The Risks of Foreign Matter Contamination in Food Manufacturing Lines and Their Countermeasures

Screws falling off the production line! Unnecessary costs incurred due to measures against loosening.

One of the issues troubling manufacturing sites is the detachment of screws used on the production line. Implementing measures to prevent loosening on-site can lead to unnecessary costs, which is a significant burden. In other words, the required measures should not only prevent screw detachment but also ensure that subsequent maintenance is easy, which is also an important factor. *For more details, you can view the related links.

Magnetic Hex Holder with Female Thread

Magnetic Hex Holder with Female Thread

A neodymium magnet with strong adhesive force is incorporated into the round nut. It can be used for adhesion of products and jigs, utilizing the screw hole.

Compared to general similar-shaped products, the magnet is larger and has a stronger adhesive force. Since the screw hole is not through, there is no worry of hitting the magnet when tightening.
