Manufactured from Grade 8.8 steel with a zinc-plated finish, this screw provides solid tensile strength and basic corrosion resistance suited to general-purpose use. The partially threaded shank follows DIN 931 and ISO 4014 standards, measuring M20 x 2.50 thread pitch with a 120 mm length under head. A 30 mm hex drive accommodates standard metric wrenching. Machinists, millwrights, fabricators, and maintenance technicians working in metric-specification environments are the primary installers of this fastener.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for metric-dimensioned steel structures, heavy equipment frames, machine bases, and general mechanical assemblies requiring a controlled-grip-length fastener. The partially threaded design allows the unthreaded shank to bear shear loads while the threaded portion engages the nut or tapped hole. Applications span manufacturing floors, agricultural equipment, construction machinery, and maintenance-repair-operations (MRO) work where DIN 931 or ISO 4014 compliance is specified. Sold individually with a minimum order quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8.8 steel construction provides a proof load of approximately 600 MPa class — suitable for medium-high-strength metric bolting\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank per DIN 931 and ISO 4014 allows shear-load bearing along the unthreaded grip zone\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers baseline corrosion protection in dry and mildly humid environments\u003c\/li\u003e\n  \u003cli\u003e30 mm hex drive accepts standard metric open-end, box, or socket wrenches\u003c\/li\u003e\n  \u003cli\u003eM20 x 2.50 thread pitch with 120 mm length under head covers a wide range of flange and structural stack-up thicknesses\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 931 and ISO 4014 dimensional standards for predictable fitment in metric-spec assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and MRO replacement fastener for metric assemblies specifying an M20 x 2.50 x 120 mm partially threaded hex head cap screw per DIN 931 or ISO 4014.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanics, millwrights, or maintenance technicians using a metric wrench or socket sized to the 30 mm hex. Always inspect mating threaded holes or nuts for clean, undamaged threads before installation. Torque to the value specified in the equipment manufacturer's service documentation for Grade 8.8 M20 fasteners — do not rely on generic torque values without verifying the joint design. Power down and de-energize any equipment before accessing fastened assemblies where required by safety procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M20 x 2.50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 120 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 30 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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 8.8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish \/ Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 931, ISO 4014\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 815250PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695811494194,"sku":"815250PR","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/280f69bd38f7c0394f4a193589a62b98.jpg?v=1788338434","url":"https:\/\/voomisupply.com\/products\/value-collection-815250pr-m20-hex-cap-screw-grade-8-8-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
