It features a 1\/4-28 unified fine thread and measures 1\/2 inch under the head, making it well-suited for applications where fine thread engagement and controlled clamping force are required. Manufactured from Grade 9 steel, this fastener delivers tensile strength well above standard Grade 5 or Grade 8 fasteners in its class. The Bowma-Guard zinc-plated clear chromate finish provides corrosion resistance for both indoor and outdoor use. This screw is typically installed by millwrights, maintenance technicians, and mechanical assemblers working in industrial, agricultural, or heavy-equipment environments.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is designed for use in assemblies requiring fine-thread engagement, including hydraulic component mounting, drivetrain housings, and structural brackets where vibration resistance is critical. The 1\/4-28 fine thread pitch allows for precise torque control and greater resistance to loosening under dynamic loads compared to coarse-thread equivalents. It is supplied in a package quantity of 100 units, making it practical for production and maintenance operations with recurring fastener demand.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 steel construction for superior tensile strength beyond standard Grade 8 fasteners\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 unified fine thread for precise torque control and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement across the full fastener length\u003c\/li\u003e\n  \u003cli\u003eBowma-Guard zinc-plated clear chromate finish for corrosion protection\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch length under head suits tight-clearance fastening applications\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 100 for production and service use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service hex head cap screw for assemblies using 1\/4-28 fine-thread fasteners in inch-measurement systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanical technicians or millwrights using a standard hex wrench or socket set. Always de-energize and lock out equipment before accessing fastened assemblies per applicable OSHA lockout\/tagout procedures. Use a calibrated torque wrench to achieve proper clamp load; consult the equipment manufacturer's torque specification for 1\/4-28 Grade 9 fasteners. Do not mix Grade 9 fasteners with lower-grade nuts or threaded inserts, as mismatched grades 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: 1\/4-28 Unified Fine (UNF)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/2 inch\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 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bowma-Guard Zinc-Plated Clear Chromate\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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: BOW36300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":51970557182258,"sku":"BOW36300","price":42.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c4c871a2da735a4937ada8c21ea479e_eea6f086-8b11-4410-9cc1-abf4c268b619.jpg?v=1789953019","url":"https:\/\/voomisupply.com\/products\/bowmalloy-bow36300-hex-head-cap-screw-1-4-28-x-1-2-in-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
