DIN 6921 Flange bolt without Serrations

Smooth flange surface | Does not damage the work piece |8.8/10.9/304/316stainless steel

YES, We Can Solve It.
DIN 6921 flange bolts feature a smooth, flat bearing surface beneath the hex head, without serrations. The integrated flange distributes the clamping load over a wider area than a standard hex head, while eliminating the need for a separate washer in many assemblies.
The Pain Point: Standard serrated bolts act like tiny files. During assembly, they bite into the material, ruining painted surfaces, damaging soft metals, and causing costly rework.
Our Solution: The Smooth Flange Design.
We removed the serrations. Our DIN 6921 smooth flange bolts provide a completely flat bearing surface. It guarantees zero surface damage while providing the load-spreading power of a built-in washer.

• Automotive: Fastening painted body panels & interiors
• Food & Medical: Crevice-free surface for easy cleaning.
• Architecture: Visible joints on railings & cabinets.
• Precision Machinery: Prevents stress cracks on aluminum/copper.
• Sealing Systems: Perfect pair for rubber washers (leak-proof).
• Control Cabinets: Protects powder-coated electrical enclosures.
