Description

The OA Self-Locking Anchor Nut is a reliable, fixed-position anchor nut designed for permanent fastening in composite materials, resins, and thin panels. The OA series features a rigid nut configuration that provides precise positioning and consistent clamp load in structural and semi-structural assemblies.

Equipped with a self-locking deformed thread, the OA anchor nut resists loosening under vibration and dynamic loads, making it well suited for aerospace, automotive, and industrial applications. Its compact design and rivet installation method allow for secure attachment in confined spaces where access is limited.
