Manufactured from Grade 5 steel with a zinc-plated finish, this fastener measures 3\/8-16 thread size with a 1-inch length under head. The zinc coating provides corrosion resistance for both indoor and moderate-exposure environments. Conforming to ASME B18.2.1, the screw follows Unified National Coarse (UNC) thread standards, making it a widely compatible choice for structural and equipment assembly work across HVAC, plumbing, electrical, and general mechanical installations.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is suited for residential and commercial service applications where a reliable, standards-compliant fastener is required. Common install scenarios include equipment mounting, bracket assembly, panel attachment, and structural connections where Grade 5 tensile strength is specified. The fully threaded body provides maximum thread engagement across the full grip length, making it appropriate for shorter-stack fastening applications where partial threading would reduce holding strength.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFully threaded body for maximum thread engagement along entire shank length\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meets standard tensile and proof-load requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in typical service environments\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread form for broad hardware compatibility\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standard\u003c\/li\u003e\n  \u003cli\u003eHex head drive accepts standard 9\/16-inch hex wrench or socket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and general-service replacement fastener for any application specifying a 3\/8-16 x 1-inch Grade 5 fully threaded hex head cap screw per ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 9\/16-inch hex socket or open-end wrench; an impact driver with appropriate socket is acceptable for non-critical clamping applications. De-energize and lock out all electrical circuits and shut off relevant fluid or gas supply lines before accessing any equipment for fastener service or replacement. Follow applicable NEC, IFGC, or IPC guidelines as required by the system being serviced. Do not substitute Grade 5 fasteners in joints that specify Grade 8 or metric-equivalent high-strength hardware.\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: 1 inch\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: Fully 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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\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\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: D30054\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51704330387762,"sku":"D30054","price":18.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c99c864886b33fc8140ba2be0452960f.jpg?v=1788421940","url":"https:\/\/voomisupply.com\/products\/value-collection-d30054-hex-head-cap-screw-3-8-16x1-grade-5","provider":"Voomi Supply","version":"1.0","type":"link"}
