It provides a durable, load-bearing 4-40 UNC threaded hole in materials that cannot support reliable threads on their own. The insert measures 0.188 inches in overall length with an insert diameter of 0.166 inches. Fabricated from stainless steel, it resists corrosion in demanding environments. Machinists, assembly technicians, and product assemblers press these inserts into a pre-drilled hole to create a permanent, metal-threaded anchor point within plastic housings, enclosures, and structural plastic components.\u003c\/p\u003e\u003cp\u003eThis insert is suited for light-duty fastening applications in plastic parts where a flush finish is required at the surface. The flush design sits even with the surrounding material surface after installation, making it appropriate for assemblies where a protruding insert would interfere with mating parts or aesthetics. It is commonly used in electronics enclosures, instrument housings, and plastic fabrications requiring a clean, flat surface. Sold in packages of 10 with a minimum order quantity of 1 package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFlush press fit design installs level with the plastic surface for clean, interference-free assemblies\u003c\/li\u003e\n\u003cli\u003e4-40 UNC thread standard compatible with standard 4-40 machine screws and fasteners\u003c\/li\u003e\n\u003cli\u003eStainless steel construction provides corrosion resistance in wet or chemically exposed environments\u003c\/li\u003e\n\u003cli\u003eRequires a 5\/32-inch drill size for proper hole preparation prior to press installation\u003c\/li\u003e\n\u003cli\u003eCompact form factor at 0.188 inches overall length suits thin-wall plastic applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a press fit threaded insert for use in plastic substrates requiring 4-40 UNC machine screw threads.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by pressing the insert into a properly sized pre-drilled hole using an arbor press or similar controlled pressing tool. Ensure the hole diameter matches the specified 5\/32-inch drill size before pressing to avoid cracking or deforming the plastic host material. Power down any assembly before installing inserts in electrical or electronic enclosures. Do not use impact methods, as uneven force can misalign the insert or damage the surrounding plastic.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.188 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Diameter\u003c\/strong\u003e: 0.166 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Size\u003c\/strong\u003e: 5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Type\u003c\/strong\u003e: Flush Press Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use On\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0005 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: E-Z LOK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 240-004-CR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"E-Z LOK","offers":[{"title":"Default Title","offer_id":67906239594802,"sku":"240-004-CR","price":19.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63f5fbfd91e44b32ee1c5416a569e533.jpg?v=1791166440","url":"https:\/\/voomisupply.com\/products\/e-z-lok-240-004-cr-4-40-unc-flush-threaded-insert-plastic","provider":"Voomi Supply","version":"1.0","type":"link"}
