Made from steel with a zinc-plated finish, this washer distributes load across the bearing surface of a bolted joint, reducing the risk of fastener pull-through and surface damage. It measures 13 mm inside diameter by 24 mm outside diameter with a 2.5 mm thickness, and carries a hardness rating of 140 HV. Sold in a 50-piece package, this washer meets DIN 125, ISO 7089, and ISO 7090 dimensional and performance standards. Machinists, maintenance technicians, pipefitters, and general contractors use this style of washer across a wide range of metric fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis flat washer is suited for residential and commercial construction, industrial equipment assembly, HVAC equipment mounting, plumbing fixture installation, and general maintenance and repair operations. Its metric sizing and compliance with DIN 125 and ISO 7089 make it a straightforward fit wherever M12 hardware is specified. The zinc-plated finish provides a baseline level of corrosion resistance appropriate for indoor and protected outdoor environments. The 50-piece package quantity suits both single-job use and light-volume service stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeets DIN 125, ISO 7089, and ISO 7090 standards for metric flat washers\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc-plated finish for corrosion resistance in typical service environments\u003c\/li\u003e\n  \u003cli\u003e140 HV hardness rating provides reliable load distribution under standard fastener torque\u003c\/li\u003e\n  \u003cli\u003e13 mm inside diameter fits M12 fasteners without excessive play\u003c\/li\u003e\n  \u003cli\u003e24 mm outside diameter and 2.5 mm thickness conform to standard DIN 125 geometry\u003c\/li\u003e\n  \u003cli\u003eSold in a 50-piece package to support both single-job and light service-stock needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M12 metric screws, bolts, and threaded rod in standard flat washer applications conforming to DIN 125, ISO 7089, and ISO 7090 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanics, millwrights, pipefitters, or any trade working with M12 metric fastener assemblies. Place the washer between the fastener head or nut and the mating surface before tightening. Ensure the fastener and washer material are compatible with the service environment to avoid galvanic corrosion, particularly in wet or dissimilar-metal applications. Torque fasteners to the values specified by the equipment manufacturer or applicable code — do not estimate torque from washer specifications alone.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: Standard Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: M12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 13 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 24 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 2.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 140 HV\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: DIN 125, ISO 7089, ISO 7090\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161807\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CD557532\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722360521010,"sku":"CD557532","price":16.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9eb229804d254afcf46914dc02a74000.jpg?v=1788590024","url":"https:\/\/voomisupply.com\/products\/value-collection-cd557532-m12-flat-washer-steel-zinc-plated-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
