Countersunk Washers
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.
Frequently Asked Questions
How do countersunk washers provide better protection against vibrations than flat washers?
- When installed, these countersunk washers push against the object for resisting vibrations.
- They essentially act as springs. Driving a threaded fastener through the centre will force the washer's sides to collapse, thus pushing against the object.
What are finishing countersunk washers?
- Finishing countersunk washers are also known as dress washers.
- These washers are machined to be sturdier and provide a better appearance than standard countersunk washers.
- Oval and flat head screws sit flush within these countersunk washers.
What are countersunk external-tooth lock washers?
These washers feature teeth that firmly grip heads of 82-degree flat head countersunk screws, preventing joints from loosening due to vibration.
What is the significance of countersunk tight-grip external-tooth lock washers?
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.
