{"title":"Dual Lock Washers","description":"\u003ch1\u003eDual Lock Washers\u003c\/h1\u003e\n\n\u003cp\u003eFULLERKREG Dual Lock Washers are wedge-locking washer pairs engineered to DIN 25201 principles — delivering permanent, vibration-proof fastening without adhesives or deformation. Available in multiple material grades and surface treatments to suit every environment, from heavy industrial to marine and corrosive applications. Each pair interlocks cam-face to cam-face: the cam angle exceeds the thread pitch angle, so the harder the joint tries to loosen, the tighter the grip.\u003c\/p\u003e\n\n\u003ch2\u003eBrowse by Material \u0026amp;
