Understanding Delayed Fracture of Screws: Basics of Delayed Fracture Due to Hydrogen Embrittlement

What is delayed fracture? Why does hydrogen embrittlement occur? What are the prevention measures? I will explain the basics of delayed fracture and hydrogen embrittlement in an easy-to-understand manner.

Are you familiar with "delayed fracture of screws"? "Delayed fracture" refers to the phenomenon where a static stress (tensile or bending load) is applied at room temperature for a certain period of time, and then it suddenly fractures without any apparent plastic deformation. Despite the absence of large or repeated loads, the bolt suddenly fails... It might be due to delayed fracture. In fact, the mechanism behind "delayed fracture" has not been fully elucidated. The phenomenon of hydrogen embrittlement is considered to be an important factor. - What is delayed fracture? What are its testing methods? - What is hydrogen embrittlement? What are the countermeasures? This is a technical document that provides a basic understanding of these topics. Please refer to the PDF for more details. As a specialist in manufacturing both bolts and nuts, our company conducts performance testing and evaluation from the development stage at our R&D center to ensure that we meet our customers' performance requirements. We are also available for technical consultations. Please feel free to reach out to us.

[Technical Data Free Offer] You can understand the basics of "Screw Performance Evaluation."

We are engaged in product development and performance evaluation to shape our customers' requests. We provide testing evaluation equipment and examples of evaluations. We will teach you the basics of performance evaluation.

Screws are small components, but they play a significant role as functional parts in "fastening." Performance evaluation is essential to shape our customers' requests. For example, we have a series of screws designed for special octagonal shapes in resin. The starting point was a customer's request for a nut that wouldn't rotate when embedded in resin. Using FEM analysis, we selected the optimal shape from 40 different designs. Collaborating with the production technology and manufacturing departments, we developed an insert nut that can withstand high torque fastening. To turn requests into reality, it is necessary to have evaluation capabilities to ensure proposed performance. During the development stage, we need to consider performance requirements and mass production feasibility, and after development, we must confirm the design performance and mass production quality, among various evaluations. Our company is equipped with various testing and evaluation facilities, including those developed in collaboration with academia. You can understand the basics of screw performance evaluation, including what kind of equipment is used and what evaluations are conducted. We also provide actual evaluation examples. Please take a look at our development and evaluation tests to shape our customers' requests. More details can be downloaded, and feel free to contact us with any inquiries.

I will teach you the basics of fastening screws for resin. <Technical materials provided>

Are you having trouble with "fastening resin"? You can fasten resin with "bolts + nuts." You will gain basic knowledge about screws specifically for resin.

Are you struggling with "fastening of resin"? With resin, you can achieve fastening using "bolts + nuts" by utilizing dedicated screws. Dedicated screws include insert nuts and insert bolts that are embedded in the resin. In softer resins compared to iron, embedded bolts or nuts can rotate together, leading to deformation or breakage of the resin. Have you ever experienced deformation of resin products due to "nut rotation"? Our original development of dedicated screws for resin (Octa Lobular(R) series) features a special octagonal head shape that ensures high torque resistance and high pull-out strength. Even when tightened with high torque, it prevents "rotation" and "pull-out," protecting resin products. You can choose from various types of insert nuts (simultaneous molding type, press-fit type, and both with caps) and insert bolts (both simultaneous molding and post-embedding options) according to your specifications. If you're wondering, "What is an insert nut?" please refer to our technical document "Basic Knowledge of Insert Nuts." It clearly explains the usage of insert nuts and compatible resins, covering the "basics of insert nuts." You can view it via PDF download.

[Case Study] You can understand the reasons for adopting high-torque insert nuts.

You can see the benefits of using the "SSOO Nut," an insert nut that is strong against pull-out and supports high torque. Examples of parts and molding methods are currently being published.

The SSOO nut is a "heat press-in type insert nut (outsert nut)" that achieves high "torque resistance performance" and "pull-out strength." It prevents the nut from rotating (spinning) or pulling out during high torque tightening, ensuring safe fastening of resin products. The SSOO nut has solved various problems for our customers. 【Case 1】 - High tightening torque is required, but the insert nut spins. → It meets tightening requirements with high torque resistance performance, fastening resin components without spinning. 【Case 2】 - To reduce weight, we want to decrease the number of screws used. → It achieves a reduction in the number of screws used with high pull-out strength while ensuring fastening strength. Additionally, it has realized many benefits such as reducing environmental impact and responding to strong vibrations. For more details, please refer to the "SSOO Nut Adoption Case Collection." If you are struggling with fastening resin at high torque, please take a look at the materials. You will understand why we were able to develop the original SSOO nut that can handle high torque tightening. Please check it out from the link.
