Vol. 11 Back to Basics Series! Introducing Various Types of Screws

This time we are going back to the basics to talk about the types of screws used by machinery. Nedzigon will focus on frequently used metric standard screws and introduce hex head screws and machine screws.

Vol. 10 Stress Corrosion Cracking: corrosion that attacks corrosion-resistant stainless steel!

Vol. 10 Stress Corrosion Cracking: corrosion that attacks corrosion-resistant stainless steel!

This is a description of "stress corrosion cracking", a problem that frequently occurs but is difficult to detect. I, Nedzigon will discuss the causes, mechanism, and countermeasures, as well as screws that are resistant to stress corrosion cracking.

Vol. 9　Sudden Bolt "Delayed Fracture"

Vol. 9　Sudden Bolt "Delayed Fracture"

The phenomenon in which a bolt that has been fastened for some time suddenly breaks is called delayed fracture. This can cause a lot of hassle, as the exterior shows no deformation and yet the bolts suddenly break. Why does delayed fracture occur? Under what conditions does it occur? How can we prevent it? Nedzigon makes it all clear to you.

Vol. 8　Why a Cross recess gets broken: What is "cam-out"?

Vol. 8　Why a Cross recess gets broken: What is "cam-out"?

Have you experienced "stripping" of a screw, where its cross recess reams out and prevents you from removing the screw? No one enjoys struggling to remove screws with pliers, right? Today, I will explain what "cam-out" is and how it causes cross recess to "strip."

Vol.5　Varieties of SUS Screws

Vol.5　Varieties of SUS Screws

Even though we call them "stainless steel screws", there are actually a variety of types of steel. Typical steels for stainless steel screws include SUS304 and SUSXM7, but there are also other stainless steel screws that have properties beyond resistance to rust.
Today, Nedzigon would like to introduce you to the main stainless steels used for screws.
You might find just the right stainless steel screw to solve the problems you're facing now.

Vol.3　Functional Screw Surface Treatments Are Not Just for Corrosion Resistance

Vol.3　Functional Screw Surface Treatments Are Not Just for Corrosion Resistance

While ferrosoferric oxide film (black oxide finishing) and Unichrome come to mind as screw surface treatments for corrosion resistance, other surface treatments for screws provide other characteristics.
Today, Nedzigon is here to talk about these functional screw surface treatments.

Vol.2　Explaining the Vocabulary of Screws

Vol.2　Explaining the Vocabulary of Screws

Dealing with screws involves a lot of specialized terminology. When you're looking up every word you don't know in reference books or on the Internet, the time gets away from you before you know it... . Nedzigon is here to help you out with a few of the most common screw-related specialized terms.
