Manufactured from Grade 9 alloy steel, this fastener delivers significantly higher tensile strength than standard Grade 5 or Grade 8 hardware, making it a reliable choice where shear and tensile loads are elevated. The 1\/4-20 thread size paired with a 1-inch length under the head provides a common, versatile profile. A clear zinc chromate finish adds corrosion resistance for use in moderately exposed environments. Machinists, millwrights, HVAC technicians, and field service professionals reach for this fastener when OEM-grade holding power is required.\u003c\/p\u003e\n\u003cp\u003eThis screw suits a wide range of trade and industrial applications including equipment mounting, bracket installation, panel fastening, and general mechanical assembly. The 1\/4-20 thread is one of the most common inch-series fastener sizes in HVAC equipment, electrical enclosures, and light structural work. Full threading along the shank provides maximum thread engagement across the entire fastened length, which is especially useful in thinner material or when a nut is used without a tapped hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank allows maximum thread engagement along the full 1-inch length\u003c\/li\u003e\n  \u003cli\u003eClear zinc chromate finish provides moderate corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 inch-series thread is compatible with standard 1\/4-20 nuts, inserts, and tapped holes\u003c\/li\u003e\n  \u003cli\u003eHex head drive accepts standard hex wrenches and sockets for fast installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use with any 1\/4-20 threaded nut, tapped hole, or threaded insert requiring Grade 9 alloy steel strength.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex socket or open-end wrench sized to the 1\/4-inch hex head. Verify that mating threads are clean and free of debris before driving. Do not exceed the rated clamp load of Grade 9 hardware by over-torquing with impact tools without a torque-limiting attachment. When installing in painted or galvanized panels, ensure thread engagement depth meets a minimum of one full diameter to maintain holding strength.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\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: Fully 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: 36004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":52033287160114,"sku":"36004","price":47.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f84cc4aee0765127ad47856da19d55d_c3177a90-0d8c-4f1e-a18d-1c2410076c43.jpg?v=1790021438","url":"https:\/\/voomisupply.com\/products\/bowmalloy-36004-hex-head-cap-screw-1-4-20-x-1-in-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
