Heico H-HLB-20 Steel Delta Protect Wedge Lock Locking & Anti-Vibration Washer M20 is designed for secure and reliable bolt fastening, especially under extreme vibration and dynamic load conditions. The wedge lock system features radial teeth that embed into the bolt surface and the mating surface as the bolt is tightened, creating a strong interlock that prevents loosening.

This product is certified for securing bolts and works reliably at both low and high preload levels, suitable even when lubricants are applied. It is reusable without any reduction in locking quality or effectiveness, and can be easily installed and removed.

Manufactured from high-quality steel with a robust Delta Protect finish and compliant with RoHS standards, this wedge lock washer is supplied as pairs and is compatible with high tensile bolts and nuts of grades 8.8, 10.9, and 12.9. The washer has an external diameter of 39 mm, inside diameter of 21.4 mm, thickness of 3.7 mm, and grade A4 material quality.

Common industrial applications for the H-HLB-20 include sectors such as mechanical engineering, wind energy technology, automotive components, agricultural and forestry machinery, as well as railway equipment, where vibration resistance is critical.
