The product complies with DIN 433 and is used where controlled load distribution is required under screw heads with a small bearing surface. It is specifically adapted for cylindrical screw heads, such as those conforming to DIN 912 \/ ISO 4762. The product is suitable for professional installations where corrosion resistance and geometric fit are crucial.\u003c\/p\u003e\n\u003ch2\u003eAREA OF APPLICATION\u003c\/h2\u003e\n\u003cp\u003eThe product is used in industry, machine construction, and marine installations. It is intended for applications where socket head cap screws are used in countersunk or confined spaces and where standard washers according to DIN 125 have too large an outer diameter. The material selection enables use in environments with high humidity, salt exposure, or chemical exposure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWatch video:\u003c\/strong\u003e \u003ca href=\"https:\/\/youtube.com\/shorts\/9T4NSSIyFeM\" target=\"_blank\" rel=\"noopener\"\u003eWhich washer should you choose?\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL SPECIFICATIONS\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eProduct type:\u003c\/strong\u003e Washer\u003cbr\u003e\u003cstrong\u003eProduct family:\u003c\/strong\u003e Small washer for cheese head screws\u003cbr\u003e\u003cstrong\u003eMaterial grade:\u003c\/strong\u003e A4\u003cbr\u003e\u003cstrong\u003eHardness class:\u003c\/strong\u003e 200 HV\u003cbr\u003e\u003cstrong\u003eStandard:\u003c\/strong\u003e DIN 433\u003cbr\u003e\u003cstrong\u003eSurface finish:\u003c\/strong\u003e Plain\u003cbr\u003e\u003cstrong\u003eEnvironment:\u003c\/strong\u003e Marine \/ Outdoor \/ Indoor\u003cbr\u003e\u003cstrong\u003eDelivery unit:\u003c\/strong\u003e Piece\u003c\/p\u003e\n\u003ch2\u003eFREQUENTLY ASKED QUESTIONS (FAQ)\u003c\/h2\u003e\n\u003ch3\u003eWhat is the difference between DIN 433 and DIN 125?\u003c\/h3\u003e\n\u003cp\u003eDIN 433 has a smaller outer diameter and is intended for cheese head screws.
