Sized M20 x 2.50 with a 130 mm length under head, this fastener is manufactured from Grade 316 austenitic stainless steel meeting Grade A4 classification. The bright, uncoated finish exposes the natural corrosion resistance of the alloy. With a 30 mm hex drive, it is ready for standard hex tooling. Compliant with DIN 933, EN 24017, and ISO 4017 standards, this screw is suited for structural, industrial, and marine-grade assembly work where dimensional accuracy and material traceability matter.\u003c\/p\u003e\u003cp\u003eThis fastener is appropriate for use in industrial machinery, marine hardware, chemical processing equipment, and outdoor structural assemblies where exposure to moisture, salt, or corrosive environments demands a high-alloy stainless fastener. The M20 coarse thread pitch and full-length threading make it compatible with standard metric hex nuts and threaded plates across a wide range of fabrication and maintenance scenarios. Mechanical contractors, millwrights, and industrial maintenance technicians commonly specify this size for flanged connections, equipment mounting, and structural steel work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 316 austenitic stainless steel for superior corrosion resistance in wet and chemically aggressive environments\u003c\/li\u003e\n\u003cli\u003eGrade A4 classification per ISO 3506, confirming alloy composition and mechanical performance\u003c\/li\u003e\n\u003cli\u003eFully threaded shaft for maximum thread engagement across the full 130 mm length under head\u003c\/li\u003e\n\u003cli\u003e30 mm hex drive compatible with standard metric wrenches and sockets\u003c\/li\u003e\n\u003cli\u003eCompliant with DIN 933, EN 24017, and ISO 4017 dimensional standards\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish with no plating that could introduce contamination or dimensional variation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a metric-standard hex head cap screw for use with M20 x 2.50 threaded nuts, inserts, and tapped assemblies conforming to DIN 933, EN 24017, and ISO 4017 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright using a calibrated torque wrench and appropriate metric hex tooling. Ensure mating threads are clean and free of debris before assembly. Do not mix metric and unified fasteners. When installing in stainless-to-stainless applications, apply an anti-seize compound to reduce the risk of galling during tightening.\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: 130 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316 Austenitic Grade A4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\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\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 933, EN 24017, ISO 4017\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HC3XX20130\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696408297778,"sku":"HC3XX20130","price":117.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/43b0045f78d3bd85af1fd6587dcb35fc.jpg?v=1788342331","url":"https:\/\/voomisupply.com\/products\/value-collection-hc3xx20130-m20-hex-cap-screw-grade-316","provider":"Voomi Supply","version":"1.0","type":"link"}
