Hex Flange Bolts vs. Separate Washers: Load Distribution and Assembly Notes

Streamlining assembly lines, improving clamping force distribution, and eliminating loose washer risks with ISO 4161 hex flange bolts.

Hex Flange Bolts vs. Separate Washers: Load Distribution and Assembly Notes

Separate spring washers in black and zinc finishes

In modern manufacturing, every second saved on the assembly line translates to thousands of dollars in profit. That is why engineers are increasingly specifying integrated hex flange bolts instead of separate bolts and flat washers.

Distributed Pressure and Anti-Spin

The widened base of a flange bolt distributes clamping pressure over a larger surface area, protecting soft materials from crushing. Serrated flange designs also provide excellent resistance against loosening.


FAQ: Flange Bolts

  • Q: Do flange bolts require washers?
    A: Generally no, as the integrated flange acts as a built-in washer, reducing inventory count and assembly time.
