Package Included:M8 Flange Hex Nuts x 25 PCS About Serrated Flange Hex Nut Flange nuts have a washer-like base to distribute pressure over a greater surface area and ensure the fastener stay tight. They have serrations that grip the material surface instead of threads for easy installation and mild vibration resistance. They are commonly used in assembly lines where operations are speeded by using a single fastener instead of a nut and a washer.
