M8 x 40mm Serrated Flange Hex Head Bolt DIN 6921 | 8.8 Steel BZP
The M8 x 40mm serrated flange hex head bolt is built for machine frame assemblies where a single fixing must clamp firmly without a separate loose flange washer. With a 40mm length, it suits thicker brackets, spacers and deeper mounting points used in equipment builds.
The 1.25mm pitch supports predictable thread engagement while the 18.0mm flange diameter increases the bearing area beneath the head. 8.8 steel with a BZP finish gives a strong zinc plated option for machinery, fabricated frames and dry industrial environments.
Common Applications
Frequent use cases include:
- Fabricated steel brackets
- Workshop repairs
- Production equipment frames
- Machine guards and access panels
