It is made of A2 \/ AISI 304 stainless steel and designed to withstand moisture, milder chemicals, and temperature fluctuations. The product's design includes a wavy washer body that provides a spring effect and compensates for movements, temperature changes, and settling in joints. It allows for easy assembly together with standard threaded fasteners such as bolts and screws. The wavy spring washer DIN 137 is used where durability and corrosion resistance are crucial – especially in industrial and outdoor environments.\u003c\/p\u003e\n\n\u003ch2\u003eFIELD OF APPLICATION\u003c\/h2\u003e\n\n\u003cp\u003eThe wavy spring washer DIN 137 is intended for preload absorption and vibration-damping fastening in environments such as wet rooms, food production, or chemical plants. The spring function creates a secure and lasting contact between the parts of the joint, which reduces the risk of the joint loosening due to vibrations or thermal expansion. The product is used together with bolts or screws – no special assembly is required, and installation is easily performed with standard hand tools. Suitable for both static and dynamic applications where preload and corrosion protection are important. The product requires minimal maintenance and has a long service life, even in humid environments.\u003c\/p\u003e\n\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\n\u003ch2\u003eTECHNICAL SPECIFICATIONS\u003c\/h2\u003e\n\n\u003cp\u003e• \u003cstrong\u003eProduct type\u003c\/strong\u003e: Spring washer\u003cbr\u003e• \u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 137 B\u003cbr\u003e• \u003cstrong\u003eQuality\u003c\/strong\u003e: A2 \/ AISI 304\u003cbr\u003e• \u003cstrong\u003eMaterial class\u003c\/strong\u003e: Not applicable\u003cbr\u003e• \u003cstrong\u003eThread type\u003c\/strong\u003e: Not applicable\u003cbr\u003e• \u003cstrong\u003eSurface treatment\u003c\/strong\u003e: Untreated (natural stainless steel)\u003cbr\u003e• \u003cstrong\u003eHead shape\u003c\/strong\u003e: Not applicable\u003cbr\u003e• \u003cstrong\u003eDrive type\u003c\/strong\u003e: Not applicable\u003c\/p\u003e\n\n\u003ch2\u003eFREQUENTLY ASKED QUESTIONS (FAQ)\u003c\/h2\u003e\n\n\u003ch3\u003eHow does a wavy spring washer (DIN 137) work and what distinguishes its design?\u003c\/h3\u003e\n\n\u003cp\u003e\u003cb\u003eDIN 137\u003c\/b\u003e specifies the standard for spring washers with a wavy (curved) profile:\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eContinuous spring force:\u003c\/b\u003e When the screw joint is tightened, the wavy profile flattens slightly and creates a constant axial preload in the joint.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eCompensates for settling:\u003c\/b\u003e The spring effect absorbs axial play and compensates for material movements caused by temperature fluctuations, vibrations, or thermal expansion.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eGentle on surfaces:\u003c\/b\u003e Unlike tooth lock washers or split spring washers (DIN 127), DIN 137 has no sharp edges that cut into or damage the contact surface under the screw head or nut.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy is DIN 137 ideal for sensitive or dynamic screw joints?\u003c\/h3\u003e\n\n\u003cp\u003eWavy washers are primarily used where you need a controlled and even clamping force rather than a rigid, hard locking:\u003c\/p\u003e\n\n\u003col start=\"1\"\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eLight metals and plastics:\u003c\/b\u003e Perfect when mounting against softer materials where sharp locking elements could otherwise cause cracking or damage the surface treatment.\u003c\/p\u003e\n\n\n\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eBall bearings \u0026amp;
