Manufactured from 18-8 austenitic stainless steel to Grade A2, this fastener offers solid corrosion resistance in wet, chemical, or outdoor environments. The 90-degree flat head seats flush with the workpiece surface when installed into a properly countersunk hole. Drive engagement is via a 2.50 mm hex socket, requiring an appropriate Allen key or hex bit driver. The M4x0.7 thread pitch and 40 mm overall length make it suitable for moderate-depth fastening tasks where a clean surface profile is required. This screw is partially threaded per DIN 7991 standards and is sold in a minimum order quantity of 25 pieces.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used across a wide range of industries including light mechanical assembly, HVAC equipment panels, electrical enclosures, plumbing fixture mounting, and general fabrication. The flush-head design is preferred wherever protruding fastener heads would interfere with mating surfaces, covers, or moving components. Installers working on stainless or aluminum panels commonly specify Grade A2 hardware to avoid galvanic incompatibility and surface staining. The metric M4x0.7 thread standard is consistent with ISO and DIN hardware used in European-specification equipment and many OEM assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 austenitic stainless steel, Grade A2 — corrosion resistant for wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003e90-degree flat head profile for flush countersunk installation per DIN 7991\u003c\/li\u003e\n  \u003cli\u003e2.50 mm hex socket drive for precise torque application with standard Allen tools\u003c\/li\u003e\n  \u003cli\u003eM4x0.7 metric thread, 40 mm overall length, partially threaded shank\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 25 pieces per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 7991 metric flat socket cap screw for use in any application requiring an M4x0.7 countersunk hex-socket fastener.

The mating hole must be properly countersunk to a 90-degree included angle to achieve full flush seating. Do not overtorque stainless steel fasteners, as galling can permanently seize the thread; anti-galling compound is commonly applied in high-cycle or precision assemblies. Follow applicable equipment manufacturer torque guidelines for M4 fasteners when available.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4x0.7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 40 mm overall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 90 degree Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 2.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 18-8 Austenitic Stainless Steel, Grade A2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: DIN 7991\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25 pieces\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: FHS1X0440-025BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723350180146,"sku":"FHS1X0440-025BX","price":1357.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a23d85dfe65721ad8ee93d7f7d790e83.jpg?v=1788603697","url":"https:\/\/voomisupply.com\/products\/value-collection-fhs1x0440-025bx-m4x0-7-flat-socket-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
