It features an M20 x 2.50 mm thread profile with a 90 mm length under the head and is partially threaded per DIN 931 standard. The 30 mm hex drive size suits standard hex wrenches and impact tooling. Grade 316 stainless provides elevated corrosion resistance compared to 303 or 304 grades, making this fastener appropriate for wet, chemical-exposure, or outdoor service environments. Machinists, pipefitters, millwrights, and marine maintenance technicians commonly specify this grade for demanding installations.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for structural and mechanical assemblies where corrosion resistance is a primary requirement. Typical applications include pipe flange connections, pump and valve mounting, food-processing equipment, marine hardware, and outdoor structural steel. The partial thread shank provides a clean bearing surface in clearance holes, which is useful when fastening thick materials or when shear load transfer is a design consideration. The bright uncoated finish leaves the base material exposed for maximum corrosion performance without galvanic interference from platings or coatings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM20 x 2.50 mm metric thread, partially threaded per DIN 931\u003c\/li\u003e\n  \u003cli\u003e90 mm length under head for clearance in thick-stock assemblies\u003c\/li\u003e\n  \u003cli\u003eGrade 316 austenitic stainless steel, A4 designation for superior chloride resistance\u003c\/li\u003e\n  \u003cli\u003e30 mm hex drive size compatible with standard hex wrenches and impact sockets\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating to flake, crack, or introduce galvanic incompatibility\u003c\/li\u003e\n  \u003cli\u003eSold individually (package quantity: 1)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 931-compliant partially threaded metric hex head cap screw.

Always confirm mating thread pitch and material compatibility before installation to avoid galling, which is common with austenitic stainless fasteners — applying an anti-seize compound rated for stainless is standard practice. Torque to the value specified in the design drawing or equipment service manual. Do not substitute torque values from carbon-steel fastener tables, as stainless steel has different yield characteristics.\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 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 90 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: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 931\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 30 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: HC1XX20090-001BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723662098738,"sku":"HC1XX20090-001BX","price":40.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dad693cebb6ad4f1ed27447c73860cfb.jpg?v=1788607284","url":"https:\/\/voomisupply.com\/products\/value-collection-hc1xx20090-001bx-m20-hex-cap-screw-316-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
