At 3 inches in length under the head and partially threaded, this fastener is built for high-strength bolted connections where a standard hex head drive is required. Grade L9 steel delivers superior tensile strength compared to common Grade 5 or Grade 8 designations, making it well suited for demanding mechanical and structural assemblies. The zinc yellow dichromate coating provides corrosion resistance and serves as a visual identifier for the grade specification. Licensed tradespeople and maintenance technicians working in industrial and mechanical applications are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in a wide range of industrial, mechanical, and equipment assembly applications where a fine-thread UNF pattern is specified. The 1\/4-28 thread pitch is commonly found in precision assemblies, automotive components, and equipment housings where vibration resistance and tight thread engagement are priorities. The partial threading allows for a smooth shank grip length, which supports shear loading in bolted joint designs. Sold in a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade L9 steel construction for high tensile strength bolted connections\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF fine-thread pattern for vibration-resistant engagement\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports shear loading in joint designs\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance and grade identification\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head suits deeper engagement or through-bolt applications\u003c\/li\u003e\n  \u003cli\u003e7\/16-inch hex key size for standard wrench or socket drive\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application specifying a 1\/4-28 UNF partially threaded hex head cap screw in Grade L9 steel with a zinc yellow dichromate finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician familiar with fastener torque requirements for Grade L9 hardware. Use a 7\/16-inch wrench or socket to drive the fastener. Inspect mating threads for damage or contamination before installation, and ensure the joint materials are compatible with the zinc dichromate finish. Follow applicable ASME or equipment manufacturer torque specifications for the joint design — do not over-torque fine-thread fasteners.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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: L9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0046 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 440068PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702078472498,"sku":"440068PR","price":679.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/415654cc2bd36f6d4b839fcef82e73dd_1c35d3ff-9ed8-4d72-9e03-d6754e1078e1.jpg?v=1788408843","url":"https:\/\/voomisupply.com\/products\/value-collection-440068pr-hex-cap-screw-1-4-28-x-3-in-grade-l9","provider":"Voomi Supply","version":"1.0","type":"link"}
