This screw features a hex head for reliable wrench engagement and a Type 1\/Type D point, which cuts its own mating thread as it is driven into unthreaded material. Constructed from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, the 31843 measures 0.5 inches in length under the hex head. It is a standard fastener used across HVAC, plumbing, electrical, and general sheet metal or structural assembly work.\u003c\/p\u003e\n\u003cp\u003eThis thread cutting screw is suited for light-gauge metal, plastic, and composite materials where a pre-tapped hole is not required. The 5\/16-18 UNC coarse thread profile provides strong thread engagement in softer base materials. Typical installation scenarios include equipment enclosures, panel assembly, ductwork, junction boxes, and similar trade applications where a self-threading fastener reduces labor and eliminates the need for a separate tapping step. Sold individually, with a minimum order quantity of 50 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread cuts its own mating thread in unthreaded material\u003c\/li\u003e\n  \u003cli\u003eType 1\/Type D point for reliable thread-forming entry without pre-tapping\u003c\/li\u003e\n  \u003cli\u003eHex head allows standard socket or wrench drive for consistent torque application\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate tensile strength for light-to-medium fastening loads\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic protection against corrosion in dry or mildly humid environments\u003c\/li\u003e\n  \u003cli\u003e0.5-inch length under hex head suits thin-gauge material stackups common in equipment assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC thread cutting fastener suitable for use in light-gauge steel, aluminum, and plastic assemblies where self-threading capability is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex wrench, socket driver, or impact tool sized for a 5\/16-inch hex head. Ensure the base material thickness and hardness are appropriate for a thread cutting application before driving. Do not overdrive — strip-out is not recoverable in thread-cut holes without helicoil repair. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener specifications in structural or pressure-boundary assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Hex\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Hex Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Type 1\/Type D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Grade 2 Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 31843\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689461678386,"sku":"31843","price":37.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53cee1708d7f497e3d314eb9df5d915d.jpg?v=1788259827","url":"https:\/\/voomisupply.com\/products\/value-collection-31843-5-16-18-unc-thread-cutting-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
