Notice of Designation for Utilization Promotion Technology for Fiscal Year 2023 - Nord-Lock Washers for Bolt Loosening Prevention

No allowance for loosening, securely maintain axial force! Physically prevent loosening of bolts/nuts.

This catalog introduces the "Nord-Lock Washer," which utilizes wedge-locking technology to prevent bolt loosening "physically" without relying on friction. We offer a lineup that includes the "Nord-Lock X Series Washers," which simultaneously prevent two types of loosening, and the "Nord-Lock SC Washers," designed for high-strength bolts used in construction. Additionally, we provide information on why bolts loosen and feature the Nord-Lock customer magazine.

Washers compatible with high-strength bolts for construction used in steel structures and bridges in Europe!

The product is a Nord-Lock washer specifically designed for high-strength bolts used in construction, easily replaceable with flat washers as specified in EN 14399-6. It is widely used in structural steelwork and bridge construction in many countries where European standards apply, physically preventing bolt loosening caused by vibrations from vehicle traffic and other sources. The chamfer treatment on the inner diameter is applied to both sides of the two-piece set, eliminating the risk of incorrect assembly orientation. 【Features】 ■ Physically prevents rotational loosening in steel structures ■ Product design specialized for HV or HR sets and CE marked ■ Allows for a highly reliable fastening design even with short fastening lengths ■ Provides the same effect regardless of the skill or experience of the operator ■ Usable in a wide temperature range from -50°C to 150°C *For more details, please refer to the PDF document or feel free to contact us.

Prevent two types of loosening simultaneously! We offer both standard and wide types for the outer diameter!

We would like to introduce the "Nord-Lock X Series Washers" that we handle. This product can prevent both "rotational loosening," which occurs due to reverse rotation, and "non-rotational loosening," which does not involve reverse rotation due to thermal expansion and contraction or surface indentation, all with a single product thanks to its unique product technology. By incorporating a disc spring shape into the wedge-locking technology in the product design, it also prevents the loss of axial force caused by "settling," which inevitably occurs in metal-to-metal fastening, thereby protecting the fastening joint at an even higher level. 【Features】 ■ Simultaneously addresses two types of loosening with a single solution ■ Allows for a highly reliable fastening joint design even with short fastening lengths ■ Stable friction coefficient due to unique technology ■ Work is completed simply by tightening through the bolt axis ■ Leads to significant reductions in workload and time *For more details, please refer to the PDF document or feel free to contact us.

We have newly added a **"Frequently Asked Questions Q&A"** section to the Hyper CLT sheet website. It clearly summarizes many questions frequently asked by those considering the introduction of the product, such as "What types of civil engineering sites can it be used on?", "Can it be used on rainy days?", "Is it compatible with large machinery?", and "What is NETIS?". The Hyper CLT sheet is a lightweight wooden sheet utilizing wood CLT, suitable for a wide range of applications including temporary roads, access routes, and heavy machinery work yards. It is also registered as a **Ministry of Land, Infrastructure, Transport and Tourism NETIS registered technology "TH-250021-A"**. Since it is a new material, we will not leave any uncertainties unaddressed. We aim to create a website that makes it easy to resolve questions before introduction, including information on wood, NETIS, civil engineering, and CLT, and we will continue to enhance the Q&A section.

We have added a new **"Glossary"** to the Hyper CLT sheet website. In the civil engineering and construction industries, there are many specialized terms such as "CLT," "NETIS," "temporary roads," and "wooden lightweight sheets." Therefore, we have introduced related terms in an easy-to-understand manner so that those who are encountering Hyper CLT sheets for the first time can understand the products and technologies. Hyper CLT sheets are wooden lightweight sheets for civil engineering that utilize wood CLT and are registered under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS technology as **"TH-250021-A."** We hope that by not only conveying the features of the product but also sharing the underlying technologies and terminology, users will feel a closer connection to Hyper CLT sheets. We will continue to enhance our website and provide clear information related to wood, NETIS, civil engineering, and CLT.

Hotron Inc. has launched its new product, the "Vehicle Count Sensor CCS3"! This product is a ceiling-mounted sensor that combines infrared and radar technology. It reliably detects vehicles in both directions with a single unit, accommodating traffic during congestion and vehicle passing, thus achieving efficient occupancy management in large parking lots. Additionally, it can be utilized for exit warning purposes in addition to vehicle counting, contributing to the safe and smooth operation of parking facilities. 'Features' - Improved detection performance against changes in road surface during rainy weather by using both infrared and radar. - Equipped with IP67 waterproof and dustproof performance, making it effective even in salt damage areas. - Various settings can be configured from a dedicated app (for Android devices), with current settings easily understandable at a glance. - The base dimensions are the same as the previous model "CCS2," allowing for smooth replacement of existing equipment. *For more details, please refer to the product information, catalog download, or contact us.*

On September 15, 2026, we issued a press release regarding the wooden lightweight sheet "Hyper CLT Sheet." The Hyper CLT Sheet is a civil engineering sheet that utilizes CLT (Cross-Laminated Timber) stacked in an orthogonal direction. It can be used in various locations such as temporary roads, access routes, heavy machinery work yards, and material storage areas. The 5×10 version weighs approximately 230 kg, making it relatively lightweight and easy to install, remove, and relocate. Additionally, it offers environmental benefits such as reducing glare and metallic sounds typical of wood, as well as CO2 fixation. Furthermore, it can be proposed for the use of new technologies in public works as a **registered technology with the Ministry of Land, Infrastructure, Transport and Tourism "TH-250021-A."** Through this press release, we aim to expand the new wooden lightweight sheet that combines wood, NETIS, civil engineering, and CLT to more construction sites.

We have published the latest issue (No. 94) of the ISO-related information magazine "Intertek News." Intertek News delivers information and various topics related to ISO audits, certifications, and verifications. This issue features a special section titled "Interpreting Standard Revisions," which introduces key points of management system standard requirements that new personnel should understand as preparation for standard revisions. Additionally, we have included customer case studies, articles contributed by auditors, and information on certifications and standards, as well as the latest topics, so please take a look.
