Each screw is manufactured from steel with a zinc-plated base and a satin black painted finish, providing corrosion resistance and a consistent decorative appearance. This fastener is designed specifically for use with heavy duty ornamental strap and T-hinges, making it the correct hardware pairing for hinge installations that demand both structural holding power and a finished look. Installers rely on lag screws of this type when securing hinges to wood framing, gates, or structural panels where a standard wood screw would not provide adequate pull-out resistance.\u003c\/p\u003e\n\u003cp\u003eThis lag screw is intended for use with the 858 Heavy Duty Ornamental Strap Hinge and the 859 Heavy Duty Ornamental T-Hinge. It is appropriate for residential and light commercial applications including wood gates, fence doors, barn hardware, and decorative door installations. The satin black finish matches the hinge hardware finish, maintaining a uniform appearance across the completed installation. The hex-head drive allows for installation with a standard socket or wrench, seating the fastener firmly without cam-out.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSized at 5\/16 inches by 1.5 inches for correct fitment with 858 and 859 series hinges\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc plating for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eSatin black painted finish matches ornamental hinge hardware\u003c\/li\u003e\n  \u003cli\u003eHex-head drive for positive wrench engagement and controlled torque application\u003c\/li\u003e\n  \u003cli\u003eSold as a 6-pack to supply a full hinge installation set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the 858 Heavy Duty Ornamental Strap Hinge and the 859 Heavy Duty Ornamental T-Hinge from NATIONAL MFG\/SPECTRUM BRANDS HHI.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a carpenter, general contractor, or experienced DIYer. Pre-drilling a pilot hole into the wood substrate is strongly recommended to prevent splitting and to ease screw seating. Use a socket wrench or nut driver sized for the hex head and avoid overtightening, which can strip the wood or damage the finish. Ensure the hinge is properly aligned before driving lag screws to final depth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Plated with Satin Black Paint\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.08 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: NATIONAL MFG\/SPECTRUM BRANDS HHI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N179-150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51561755967794,"sku":"N179-150","price":24.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03d2cd9c58d4831c47141b9c5def7209.jpg?v=1786468385","url":"https:\/\/voomisupply.com\/products\/national-mfg-n179-150-lag-screw-5-16x1-5-in-black-steel-6pk","provider":"Voomi Supply","version":"1.0","type":"link"}
