Measuring 1-8 thread size by 3-1\/2 inches in length under the head, this screw features a zinc-plated clear chromate finish that provides corrosion resistance in moderate-exposure environments. The partial threading pattern is suited for clamping applications where a smooth shank is required for proper joint alignment. Licensed tradespeople and maintenance technicians working in heavy equipment, OEM machinery, and structural fabrication rely on this grade for demanding load requirements.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in Inch-system assemblies requiring a high-torque, high-clamp-load fastener. Grade 9 alloy steel offers greater tensile strength than the more common Grade 5 and Grade 8 designations, making it appropriate for hydraulic equipment, off-highway machinery, and heavy-duty mechanical joints. The zinc clear chromate coating provides a baseline level of corrosion protection for indoor or light-outdoor service environments. Package quantity is 10 units per pack.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 alloy steel construction for elevated tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated clear chromate finish for corrosion resistance in moderate environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for accurate clamping and joint alignment\u003c\/li\u003e\n  \u003cli\u003e1-8 thread size with 3-1\/2 inch length under head for deep-reach fastening\u003c\/li\u003e\n  \u003cli\u003eInch measurement system compatible with standard SAE tooling\u003c\/li\u003e\n  \u003cli\u003eSold in packs of 10 units to match typical service quantities\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for Inch-system assemblies requiring a 1-8 thread size, Grade 9 alloy steel hex head cap screw with partial threading.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright familiar with high-strength fastener procedures. Always verify thread engagement depth and mating material compatibility before torquing. Use calibrated torque tooling appropriate for Grade 9 fasteners and follow the applicable equipment manufacturer torque specifications. Inspect threads for damage and ensure the mating nut or tapped hole meets the required strength grade before assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 (Inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Clear Zinc Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: BOWMALLOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 36219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":51974227165490,"sku":"36219","price":146.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6024124ef0b2d44d41db1c649ffbaad3_72b8f1fa-0758-42eb-ac3c-dae51f2a9473.jpg?v=1789976459","url":"https:\/\/voomisupply.com\/products\/bowmalloy-36219-hex-head-cap-screw-1-8-x-3-1-2-in-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
