It features an M8-1.25 thread with a 60 mm nominal length and 50 mm of usable thread length measured from under the head. The bolt is produced from Grade 10.9 alloy steel, delivering high tensile strength suited for demanding fastening applications. A phosphate and oil finish provides baseline corrosion resistance and lubricity during installation. The integrated smooth flange, measuring 35 mm in diameter, distributes clamping load across a wider bearing surface without requiring a separate washer.\u003c\/p\u003e\u003cp\u003eThis bolt is suited for structural and mechanical assemblies where metric fasteners meeting DIN 6921 are specified. Typical applications include heavy equipment, automotive subframes, industrial machinery, and structural steel connections where a flanged hex fastener is required to replace or supplement a standard bolt-and-washer stack. Installation is performed by qualified mechanics, millwrights, or assemblers working to metric torque specifications defined by the engineer of record or equipment OEM documentation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 10.9 alloy steel construction for high tensile strength and fatigue resistance\u003c\/li\u003e\n\u003cli\u003eSmooth 35 mm flange diameter distributes load, eliminating the need for a separate flat washer\u003c\/li\u003e\n\u003cli\u003eM8-1.25 thread, 50 mm thread length measured under head, per DIN 6921\u003c\/li\u003e\n\u003cli\u003ePhosphate and oil finish provides corrosion resistance and reduces installation friction\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6921 and DIN ISO 898-1 fastener standards\u003c\/li\u003e\n\u003cli\u003eHex drive with 20.67 to 21.00 mm drive size for standard metric tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 6921-compliant replacement or service fastener for metric assemblies specifying an M8-1.25 hex flange bolt at Grade 10.9.

Apply torque values specified by the equipment OEM or structural engineer — do not use generic torque tables without confirming the joint design, lubrication condition, and required clamp load. Inspect the flange seating surface for burrs or debris before tightening to ensure full bearing contact. Do not re-use fasteners that show thread deformation, corrosion, or evidence of yielding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8 x 1.25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 50 mm (measured under head)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Length\u003c\/strong\u003e: 60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 20.67 to 21.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Type\u003c\/strong\u003e: Smooth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 35 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 10.9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Phosphate and Oil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6921, DIN ISO 898-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 427927MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722285023538,"sku":"427927MSC","price":10672.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1a95d3d8f57def43c85e48b48d36674.jpg?v=1788588646","url":"https:\/\/voomisupply.com\/products\/value-collection-427927msc-hex-flange-bolt-m8-1-25-grade-10-9","provider":"Voomi Supply","version":"1.0","type":"link"}
