How often do you find the panels you mount end up with the holes flogged out?
Whether it's Go-karts, Motorcycles or Race Cars, we often use these panel mounting washers.
The problem we found is that when clamping softer materials such as composites, plastics etc the clamping load alone is not sufficient, the vibration & twisting forces often flog out the hole where the fastener passes through.
The fastener thread or shank knocks out the internal hole surfaces.
Simple but effective, we designed the washer with a larger locating shoulder on the underside. This provides better lateral support for the panel & reduces the bearing load by increasing the panels hole surface area.
This means less movement & reduced wear.
So we are currently making these from aircraft alloy to suit M5, M6 & M8 countersunk fasteners,
Streamlined to reduce aerodynamic drag.
Have a 12x2mm locating shoulder on the underside.
