Notice of NETIS Registration - SC Washers for Bolt Loosening Prevention in Construction
We are pleased to announce that one of our Nord-Lock washer product lines, the "SC Washer for Construction," has been officially registered with the Ministry of Land, Infrastructure, Transport and Tourism's New Technology Information System (NETIS).
NETIS Registration Date: February 2023
NETIS Registration Number: KKK-190002-A
NETIS Registered Technology Name: Nord-Lock SC Washer
The Nord-Lock SC Washer is a product specifically designed for the construction industry. Each inner diameter is chamfered to optimize the contact surface between the HV bolt and washer, which features a unique arc shape. It can be directly replaced with standard chamfered washers (compliant with European standard EN 14399-6).
Since it retains the wedge locking mechanism of the standard Nord-Lock washer, it prevents loosening through bolt axial force without relying on friction.
Our standard Nord-Lock washer was registered with NETIS in February 2020 and has been adopted in domestic applications such as road construction, lighting installations, and bridge repair works.
