Machined from Grade 8 steel with a zinc yellow dichromate finish, it provides corrosion resistance and meets the demanding requirements of UNF thread systems. The 9\/16-18 thread size and 1-3\/4 inch length under head make it well-suited for tight-tolerance bolted joints where fine thread engagement and clamping strength are critical. This fastener conforms to ASME B18.2.1 and SAE J429 standards, making it a specification-grade choice for professionals who need documented compliance.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used across a wide range of trade and industrial applications including HVAC equipment mounting, mechanical equipment frames, pump and motor assemblies, and general structural bolting where Grade 8 strength is specified. The UNF fine thread pattern offers greater tensile strength and improved resistance to loosening under vibration compared to coarse thread equivalents. It is installed with a 13\/16 inch hex wrench or socket and is appropriate wherever a fine-thread, high-strength fastener is called for in inch-measurement assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets SAE J429 minimum proof load and tensile strength requirements\u003c\/li\u003e\n  \u003cli\u003eFully threaded 9\/16-18 UNF shank provides maximum thread engagement over the full 1-3\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish adds corrosion resistance and is visually distinguishable from lower-grade fasteners\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for consistent fit in precision assemblies\u003c\/li\u003e\n  \u003cli\u003e13\/16 inch hex key size compatible with standard sockets and box wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a specification-grade replacement or service fastener for any inch-measurement bolted assembly requiring a 9\/16-18 UNF fully threaded hex head cap screw with Grade 8 strength and zinc dichromate finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson using a calibrated torque wrench sized for a 13\/16 inch hex drive. De-energize and lock out all equipment before servicing fastened assemblies per applicable OSHA lockout\/tagout procedures. Inspect mating threads for damage or contamination before installation. Do not mix Grade 8 fasteners with mismatched nuts or washers of lower strength grades, as this can result in joint failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Fully 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: Grade 8\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: 13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 454402PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694613889330,"sku":"454402PS","price":6411.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97dd35f581be6887e7a6e5b996ccf1f0.jpg?v=1788326293","url":"https:\/\/voomisupply.com\/products\/value-collection-454402ps-hex-head-cap-screw-9-16-18-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
