The screw features an M30 x 3.50 thread profile with a 120 mm length under head and is partially threaded, allowing for controlled clamp load in bolted joints. Manufactured from alloy steel to a 12.9 material grade, this fastener delivers high tensile strength suitable for demanding load-bearing connections. The black oxide finish provides moderate corrosion resistance and reduces light reflection on the fastener surface. Installation requires a hex key or Allen-type socket driver. Licensed mechanics, millwrights, and maintenance technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis screw is suited for heavy-duty machinery assembly, die and mold work, hydraulic component mounting, and structural steel fabrication where metric high-strength fasteners are specified. Its partial threading allows the unthreaded shank to act as a precision locating element in close-tolerance bores. Conformance to DIN 912 and ISO 898-1 standards makes it appropriate for applications where fastener grade documentation is required. The M30 coarse thread pitch is the standard series for this diameter in metric fastener systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM30 x 3.50 coarse thread, 120 mm length under head\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for precision fit and controlled clamping\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction rated to 12.9 material grade for high tensile strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating for moderate corrosion resistance and surface protection\u003c\/li\u003e\n\u003cli\u003eHex socket drive for high-torque installation in confined spaces\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 912 and ISO 898-1 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard metric hex socket cap screw for use in applications specifying DIN 912 geometry and ISO 898-1 grade 12.9 fasteners with an M30 x 3.50 thread profile.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with metric fastener torque requirements for grade 12.9 hardware. Always verify thread engagement depth and bore condition before installation. Use a calibrated torque wrench and the appropriate hex key socket sized for M30 cap screws. Inspect the fastener seating surface and mating threads for damage or contamination before final assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M30 x 3.50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 120 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\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: 12.9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: DIN 912, ISO 898-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 3\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: -42808-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699304268082,"sku":"-42808-6","price":80.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97fc303b8c97b213059df65fed99d1ea.jpg?v=1788374818","url":"https:\/\/voomisupply.com\/products\/value-collection-42808-6-m30-hex-socket-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
