It measures 2-3\/4 inches under the head and uses a Unified National Coarse (UNC) thread form. The zinc coating provides basic corrosion resistance for general indoor and light-duty outdoor fastening applications. This screw is driven with a 9\/16-inch hex key or wrench and is suited for use by maintenance technicians, mechanical contractors, and trade professionals requiring a standard inch-series fastener for structural and equipment assembly work.\u003c\/p\u003e\n\u003cp\u003eThis fastener is appropriate for general-purpose mechanical assembly, equipment mounting, and structural connections in residential and light commercial trade applications. Grade 2 steel is commonly used in low- to medium-stress applications where high-tensile fasteners are not required. The partial threading allows for a smooth shank section near the head, which is useful when clamping two unthreaded members together. It is a standard inch-series UNC fastener stocked for everyday maintenance and repair tasks across HVAC, plumbing, and electrical trade work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread form for compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e2-3\/4-inch length under head provides adequate grip for typical mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows solid clamping without thread engagement through both members\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for general-purpose, low- to medium-stress fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic corrosion resistance for dry and light-exposure environments\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch hex drive size compatible with standard wrenches and sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC inch-series hex head cap screw suitable for use wherever a 3\/8-16 partially threaded fastener is specified in mechanical, HVAC, plumbing, or electrical equipment assembly.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 9\/16-inch open-end, box, or socket wrench. Ensure mating nuts or tapped holes are clean and free of debris before driving. Do not over-torque Grade 2 fasteners, as the lower tensile rating makes them more susceptible to yield than Grade 5 or Grade 8 hardware. Follow applicable equipment manufacturer torque specifications and relevant mechanical codes when used in structural or pressure-boundary applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 9\/16 inches\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: 0.1 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 403120PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715344433458,"sku":"403120PR","price":3564.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7ef80f11780beb155a19bef50c3fb06.jpg?v=1788512405","url":"https:\/\/voomisupply.com\/products\/value-collection-403120pr-hex-head-cap-screw-3-8-16-x-2-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
