The K-Lock design combines a standard hex nut with a serrated external tooth washer bonded to the bearing face, providing vibration-resistant clamping without a separate loose washer. The M4x0.7 metric thread and 7 mm width across flats make it compatible with standard M4 fastener hardware. The zinc plating provides corrosion resistance for general-purpose use. Licensed tradespeople and assembly technicians working on light mechanical, electrical panel, or equipment installations will find this a practical one-piece fastening solution.\u003c\/p\u003e\u003cp\u003eThis K-Lock nut is suited for residential and commercial equipment assembly where vibration loosening is a concern. Typical applications include control panel assembly, sheet metal enclosures, electrical junction boxes, and light-duty mechanical assemblies requiring metric M4 fasteners. The external tooth washer bites into the mating surface on torque-down, resisting rotational loosening under dynamic loads. Minimum order quantity is 100 pieces per order, sold as a single package quantity of one unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIntegrated external tooth lock washer eliminates need for a separate loose washer\u003c\/li\u003e\n\u003cli\u003eM4x0.7 metric thread for compatibility with standard M4 metric hardware\u003c\/li\u003e\n\u003cli\u003eZinc plating provides general-purpose corrosion resistance\u003c\/li\u003e\n\u003cli\u003e7 mm width across flats fits standard metric hex tooling\u003c\/li\u003e\n\u003cli\u003e8.2 mm washer diameter provides secure bearing surface engagement\u003c\/li\u003e\n\u003cli\u003eOne-piece K-Lock design speeds installation in high-volume assembly work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard metric M4x0.7 K-Lock fastener for use in general mechanical, electrical, and equipment assembly applications requiring an integrated external tooth lock washer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by hand-threading onto an M4x0.7 male fastener and tightening with a standard 7 mm hex wrench or nut driver. Ensure the mating surface is clean and free of coatings that may reduce the grip of the external teeth. Do not reuse K-Lock nuts after removal, as the tooth engagement and locking performance degrade once the serrations have been compressed. Always de-energize electrical assemblies before working inside enclosures or panels.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4x0.70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: K-Lock Nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Washer Type\u003c\/strong\u003e: External Tooth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 7 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Diameter\u003c\/strong\u003e: 8.2 mm\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 525032PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700521337138,"sku":"525032PS","price":2521.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/606e0fade94af656c6a92f9ef997033a.jpg?v=1788391452","url":"https:\/\/voomisupply.com\/products\/value-collection-525032ps-m4x0-7-k-lock-hex-nut-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
