Great question! The Wedge Lock Washer does work in through bolted connections. They work well on typical painted surfaces and have been tested up to 400 micrometers thick on finishes such as: powder coat, synthetic resins, and sprayed ACEDUR varnish coatings. The key to success is the washer serrations must imprint and grip into the coated surface. ~Randy

Does this product work on through bolted connections? What about painted/coated surfaces?
