It measures M20 x 2.50 thread pitch with a 40 mm length under head and is fully threaded along that entire length. The 30 mm hex drive size accommodates standard metric wrenches. Conforming to DIN 933, this fastener is suited for structural and mechanical assemblies where corrosion resistance is a priority. Licensed tradespeople and maintenance technicians working in wet, chemical, or marine-adjacent environments commonly specify Grade 316 hardware for its superior chloride resistance compared to Grade 304.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in a wide range of trade and industrial applications including HVAC equipment mounting, plumbing support structures, pool and spa mechanical enclosures, and electrical panel assemblies exposed to moisture or corrosive atmospheres. The fully threaded configuration makes it practical for through-bolting applications where maximum thread engagement is needed across varying material thicknesses. Its metric sizing and DIN 933 compliance make it a standard choice on equipment with metric fastener specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 austenitic stainless steel (Grade A4) provides strong resistance to corrosion and oxidation\u003c\/li\u003e\n  \u003cli\u003eFully threaded M20 x 2.50 shank, 40 mm length under head for maximum engagement\u003c\/li\u003e\n  \u003cli\u003e30 mm hex drive size compatible with standard metric wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no galvanic coating to degrade in wet or chemical environments\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 933 dimensional standard for consistent interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 933-compliant M20 x 2.50 hex head cap screw for use in any assembly requiring a fully threaded metric fastener in that size and thread pitch.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, pipefitter, or maintenance technician familiar with metric fastener specifications. Always confirm thread pitch and engagement depth before final assembly to avoid cross-threading. When fastening into dissimilar metals, consider the potential for galvanic interaction even with stainless steel hardware. Follow applicable mechanical codes and equipment manufacturer torque guidance for the specific assembly.\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: 40 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\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\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\u003eDimensional Standard\u003c\/strong\u003e: DIN 933\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\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: HC3XX20040-001BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699891962162,"sku":"HC3XX20040-001BX","price":34.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36f442261616bedb6f6c4284178cad35_57e52eb7-692b-47c5-a816-432731931bf0.jpg?v=1788382682","url":"https:\/\/voomisupply.com\/products\/value-collection-hc3xx20040-001bx-m20-hex-cap-screw-316-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
