It features an M20 x 2.50 thread profile with a 90 mm length under head, manufactured from Grade 8.8 steel in a bright, uncoated finish. The screw is fully threaded along its entire shank and conforms to DIN 933 and ISO 4017 standards, ensuring dimensional consistency for use in precision assemblies. Weighing 0.573 pounds per unit, this fastener suits medium-to-heavy-duty bolted connections where a standardized metric hex drive is required. Technicians and tradespeople working with metric-spec equipment will find this screw a direct fit for a wide range of structural and mechanical joint applications.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for use in industrial machinery, structural steel assemblies, HVAC equipment mounting, and mechanical systems that call for metric M20 fasteners. The fully threaded design maximizes thread engagement across the full fastened length, making it appropriate for through-bolt applications and joints where nuts are used on both sides of a connection. The Grade 8.8 steel construction provides a reliable strength level for demanding service conditions without the added cost of higher-alloy grades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM20 x 2.50 metric thread profile, 90 mm length under head\u003c\/li\u003e\n\u003cli\u003eFully threaded shank per DIN 933 and ISO 4017 standards\u003c\/li\u003e\n\u003cli\u003eGrade 8.8 steel construction for reliable medium-to-heavy-duty load bearing\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for indoor and controlled-environment use\u003c\/li\u003e\n\u003cli\u003e30 mm hex drive size for standard metric wrench and socket compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard metric hex head cap screw for any application requiring an M20 x 2.50 x 90 mm fastener conforming to DIN 933 or ISO 4017 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson using a calibrated torque wrench sized for a 30 mm hex fastener. De-energize or lock out any equipment before fastener removal or replacement in live assemblies. Apply thread lubrication only if called for by the joint specification, as dry-torque values differ from lubricated values. Always verify that mating threads and bearing surfaces are clean and free of damage before assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 90 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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: Bright \/ Uncoated\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 933, ISO 4017\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.573 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 643241PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":67640279499058,"sku":"643241PS","price":31.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/afbc12431e2d4051984a658386f936f8.jpg?v=1790454728","url":"https:\/\/voomisupply.com\/products\/value-collection-643241ps-hex-head-cap-screw-m20-x-2-50","provider":"Voomi Supply","version":"1.0","type":"link"}
