Countersunk washers are used with oval and flat head screws to provide a bearing surface and sealing functionality. Raptor Supplies offers a wide range of countersunk washers from brands like Grainger and Micro-Plastics. These washers work similar to flat washers, but feature a bearing surface for flat head screws.
These washers feature teeth that firmly grip heads of 82-degree flat head countersunk screws, preventing joints from loosening due to vibration.
The teeth on these washers bite deeper into the screw head & joint than normal external-tooth lock washers. They provide a solid hold, preventing 90-degree countersunk screws from loosening due to vibrations.
