Product Overview
The Hex Flange Bolt with serration combines an integrated flange with anti-rotation teeth for exceptional vibration resistance.
Key Features
Serrated flange bites into mating surfaces to prevent loosening under constant vibration.
Integrated washer design eliminates the need for separate hardware, reducing assembly steps.
Available in metric (M5-M16) and imperial (#10-5/8") sizes.
Standard hex head allows for quick installation with common tools.
