Product Overview
The Hex Flange Bolt without serration provides broad, even load distribution without damaging soft or finished surfaces.
Key Features
Smooth, flat flange distributes clamping force evenly to protect delicate materials.
Integrated washer design reduces part count and speeds up installation.
Sizes range from metric (M5-M20) to imperial (#10-3/4") for versatile use.
Standard hex head enables secure torque application without surface marring.
