The internal teeth bite into the mating surface and fastener head to resist loosening caused by vibration and torque. Built from Grade 18-8 Austenitic A2 stainless steel, this washer delivers solid corrosion resistance in wet, outdoor, or chemically exposed environments. It measures 5.3mm inside diameter and 10.0mm outside diameter with a 0.6mm thickness, and ships uncoated. The pack contains 100 washers, making it practical for production assembly, maintenance kits, or field service use.\u003c\/p\u003e\n\u003cp\u003eThis lock washer is suited for M5 fastener assemblies across a wide range of mechanical and industrial applications, including HVAC equipment mounting, plumbing fixture installation, electrical panel assembly, and general equipment fabrication. The 18-8 A2 stainless grade makes it appropriate for environments where mild to moderate corrosion resistance is required, such as coastal installations, process piping, or outdoor enclosures. Installers working with stainless fastener assemblies typically select this washer to maintain consistent clamp load under vibration-prone conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal tooth design grips both the fastener head and mating surface to resist rotational loosening\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 Austenitic A2 stainless steel construction for corrosion resistance without coating\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no risk of coating delamination affecting electrical continuity or fit\u003c\/li\u003e\n  \u003cli\u003e5.3mm ID sized for M5 screw clearance fit\u003c\/li\u003e\n  \u003cli\u003e0.6mm thickness maintains a low stack height in tight assemblies\u003c\/li\u003e\n  \u003cli\u003ePack of 100 units supports production-volume and bulk service use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M5 screws and bolts requiring an internal tooth lock washer.

Ensure mating surfaces are clean and free of debris before assembly to allow full tooth engagement. Stainless steel fastener assemblies can be susceptible to galling; use appropriate anti-seize compound on the fastener threads where required. Follow applicable mechanical or electrical codes for torque and fastener specifications in the specific application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Type\u003c\/strong\u003e: Internal Tooth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8 Austenitic Grade A2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5.3mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 10.0mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.6mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 washers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161801\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: SIW7X0500-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694945141042,"sku":"SIW7X0500-100BX","price":1097.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a610a504e83ae32ebf6a6f24955276c.jpg?v=1788329870","url":"https:\/\/voomisupply.com\/products\/value-collection-siw7x0500-100bx-m5-lock-washer-ss-18-8","provider":"Voomi Supply","version":"1.0","type":"link"}
