It features an M20 x 2.50 thread profile with a 65 mm length under the head and a 30 mm hex drive. The bright, uncoated finish retains the natural surface of the 316 stainless alloy, offering strong resistance to corrosion and oxidation. This fastener conforms to DIN 933, EN 24017, and ISO 4017 standards, making it a direct fit for metric assemblies requiring certified dimensional compliance. Licensed tradespeople and maintenance technicians in mechanical, plumbing, marine, and industrial service applications regularly specify this grade for demanding environments.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for metric structural and mechanical assemblies in environments where corrosion resistance is critical, including marine installations, chemical processing equipment, food-service infrastructure, and outdoor or wet-location mechanical systems. The fully threaded shank allows engagement along the entire fastener length, which is useful when threading into blind holes or when maximum clamping adjustment is required. Plumbers, pipefitters, millwrights, and industrial maintenance technicians typically use fasteners of this specification when assembling flanged pipe connections, equipment mounts, and machinery frames that require metric-rated hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM20 x 2.50 metric thread, fully threaded shank for maximum engagement flexibility\u003c\/li\u003e\n\u003cli\u003e65 mm length under head accommodates medium-depth metric assemblies\u003c\/li\u003e\n\u003cli\u003e30 mm hex drive size for standard metric wrenches and sockets\u003c\/li\u003e\n\u003cli\u003eGrade 316 Austenitic A4 stainless steel provides superior corrosion resistance compared to Grade 304\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 933, EN 24017, and ISO 4017 dimensional and tolerance standards\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains base alloy properties with no coating thickness variation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a metric-standard replacement or service fastener for assemblies requiring M20 x 2.50 hex head cap screws conforming to DIN 933, EN 24017, or ISO 4017 specifications in Grade 316 stainless steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified tradesperson familiar with metric fastener torque requirements for the specific joint material and application. Always verify thread engagement depth and mating thread condition before installation. Use a calibrated torque wrench sized for a 30 mm hex drive to achieve the correct clamp load for the assembly. Do not mix stainless steel fasteners with dissimilar metals in submerged or high-chloride environments without verifying galvanic compatibility.\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: 65 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\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\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\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\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: HC3XX20065-001BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706208420146,"sku":"HC3XX20065-001BX","price":33.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36f442261616bedb6f6c4284178cad35_c9cd25a2-f2c7-45e1-8b2f-167ae72af113.jpg?v=1788433275","url":"https:\/\/voomisupply.com\/products\/value-collection-hc3xx20065-001bx-m20-hex-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
