Built to Grade 8.8 steel specifications, this fastener delivers reliable tensile and yield strength suited to structural bolted connections and machine assembly work. The screw features partial threading along its 180 mm shank length, with a 30 mm hex head drive size for use with standard hex wrenches or impact tooling. It conforms to DIN 931 and ISO 4014 dimensional standards, making it a recognized specification part for engineers and maintenance technicians working with metric fastener systems.\u003c\/p\u003e\u003cp\u003eThis fastener is commonly used in manufacturing, fabrication, construction, and maintenance environments where metric-standard Grade 8.8 hardware is specified. Typical applications include structural steel connections, equipment mounting, machinery assembly, and fixture fabrication. Partial threading is appropriate where clamping length and shank clearance in the joint are required by design. The DIN 931 and ISO 4014 standards govern its dimensional tolerances, thread form, and mechanical properties, ensuring interchangeability with other compliant components in the same specification class.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8.8 steel construction meets DIN 931 and ISO 4014 mechanical property requirements\u003c\/li\u003e\n\u003cli\u003eM20 x 2.50 metric coarse thread form for broad compatibility with standard metric nuts and tapped holes\u003c\/li\u003e\n\u003cli\u003e180 mm length under head with partial threading to maintain shank clearance through joint material\u003c\/li\u003e\n\u003cli\u003e30 mm hex head drive size accommodates standard open-end, box, or socket wrenches and impact sockets\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no plating or coating to affect dimensional tolerances or introduce hydrogen embrittlement risk\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 931 and ISO 4014 compliant metric hex head cap screw suitable for use with standard M20 x 2.50 metric coarse hex nuts and tapped bores conforming to the same thread standard.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanical or structural trades familiar with metric fastener specification and torque requirements. Always verify that mating thread form, pitch, and material grade are compatible before assembly. Consult applicable engineering specifications or industry torque tables for proper clamp load targets — do not rely on generic torque values for Grade 8.8 hardware without confirming joint design requirements. Inspect threads for damage before installation and do not install in corroded or cross-threaded bores.\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: 180 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\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\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\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 931, ISO 4014\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.979 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: 644268PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702457565490,"sku":"644268PS","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8403b1fa232c7f46da3013c72d63f49b.jpg?v=1788410965","url":"https:\/\/voomisupply.com\/products\/value-collection-644268ps-m20x2-5-hex-cap-screw-180mm-grade-8-8","provider":"Voomi Supply","version":"1.0","type":"link"}
