Understanding Hydrogen Embrittlement

  When choosing the right locknut and coating for your assembly, there are many things to consider. One common concern is hydrogen embrittlement. But what exactly is hydrogen embrittlement, how can a locknut be compromised due to this, and how can you stop it? The Problem Hydrogen embrittlement is a form of corrosion that weakens locknuts and may cause them to crack when under heavy loads. A ...Read More

The Importance of Corrosion Resistance Locknuts

  According to G2MT Laboratories in 2016 alone, “corrosion will cost the US economy over 1.1 trillion dollars,” and that’s without measuring the damage it can do to a company’s reputation. No matter the industry, accidents and mishaps related to metal corrosion of equipment and materials is a substantial risk. Fortunately, technological advances have led to the creation of chemical compounds and ...Read More

Flange Hex Locknuts vs. Hex Locknuts – Benefits of the Flange

In the vast majority of threaded fastener applications, there are valid reasons for opting for nuts or locknuts with flanges instead of using the “un-flanged” nut with a washer.  If the application calls for a deflected-thread all-metal locknut, there are additional reasons.  This blog entry will identify those reasons and provide supporting arguments....Read More

Torque-Tension Repeatability of Prevailing Torque Locknuts

For prevailing torque locknut applications where assembly and in-service performance are critical, it becomes appropriate to enhance the requirements and qualification tests of the locknut, beyond what may be called for in a consensus locknut standard.  One common requirement enhancement is Torque-Tension Repeatability.  Though the concept of this performance metric is easy to understand, ...Read More

Prevailing Torque Locknuts - What Zinc Flake Coatings Do to Prevailing Torque

Since RoHS became effective in the European Union in 2006, there has been a global push to eliminate Cadmium (among other substances) from use in fasteners.  Cadmium plating provides a level of lubricity that helps prevent galling in all-metal locknuts, and contributes to a more consistent torque tension characteristic in threaded assemblies....Read More
