Built from Grade 8.8 steel with a zinc-plated finish, this screw measures M20 x 2.50 thread pitch with a 70 mm length under the head and is partially threaded. The 30 mm hex drive makes it compatible with standard metric wrenches and sockets. It conforms to DIN 931 and ISO 4014 dimensional standards, making it a reliable choice for engineers, millwrights, maintenance technicians, and fabricators who require a traceable, spec-compliant fastener for structural or machinery assemblies.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for medium-to-heavy-duty bolted joint applications in industrial machinery, structural steel fabrication, equipment mounting, and general mechanical assembly. Its partial thread design provides a smooth shank section, which is preferred in applications requiring a bolt to pass through a clearance hole before engaging the threaded joint. It is sold individually and is appropriate wherever a metric M20 coarse-thread fastener meeting DIN 931 or ISO 4014 is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8.8 steel construction provides high tensile strength for demanding bolted joint applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers baseline corrosion resistance in dry and mildly humid environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows precise clamping without thread engagement through clearance holes\u003c\/li\u003e\n  \u003cli\u003e30 mm hex size accommodates standard metric wrenches and impact sockets\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 931 and ISO 4014 standards for dimensional and mechanical consistency\u003c\/li\u003e\n  \u003cli\u003eMetric M20 x 2.50 coarse thread pitch for broad tooling and nut compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard DIN 931 and ISO 4014 compliant M20 x 2.50 hex head cap screw, compatible with any M20 coarse-thread nut or tapped hole meeting the same metric thread standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, maintenance technicians, or mechanical assemblers using a metric wrench or impact socket sized for a 30 mm hex. Always de-energize and lock out equipment before fastener replacement in machinery applications. Torque to the value specified in the equipment manufacturer documentation or applicable engineering specification — do not apply an assumed torque value. Inspect mating threads and seating surfaces for damage before installation.\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: 70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 30 mm\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 815978PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716009591090,"sku":"815978PS","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db27213d463d621acc8add26c000db8d.jpg?v=1788520922","url":"https:\/\/voomisupply.com\/products\/value-collection-815978ps-m20-hex-cap-screw-grade-8-8-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
