Duratool No.4/M3 Steel Captive 'U' Nut Clip Fasteners Pack of 100

Duratool No.4/M3 Steel Captive U-Nut Clip Fasteners provide a robust, threaded fixing solution in a pack of 100 for securely joining panels. These steel captive U-nut clips create a permanent female thread in sheet metal and plastic panels where a conventional nut and bolt would be impractical.

Overview

Constructed from durable steel, these clips offer a strong and vibration-resistant hold. A generous lead-in design allows for easy and quick assembly, helping to reduce installation time. They are intended for use with standard M3 or No. 4 self-tapping screws, providing a fast fixing without the need for additional tools to hold a nut in place.
