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.
