Sized at 5\/16-18 x 1-3\/4 inches with a Unified National Coarse (UNC) thread form, this fastener is manufactured from Grade 5 steel and finished with a zinc plating for corrosion resistance. The partial thread configuration allows for clamping force to develop across unthreaded shanks in bolted joint applications. HVAC, plumbing, and mechanical contractors regularly use Grade 5 hex cap screws for equipment mounting, bracket assembly, and panel attachment tasks.\u003c\/p\u003e\n\u003cp\u003eThis fastener suits residential and light commercial trade applications where a 5\/16-18 UNC thread pattern is specified. Typical uses include securing equipment mounting feet, attaching junction boxes, anchoring pipe hangers, and general mechanical assembly on service panels and structural supports. The zinc-plated finish provides a baseline level of corrosion resistance appropriate for indoor and semi-exposed environments. This screw meets ASME B18.2.1 dimensional standards, making it a reliable drop-in fit wherever that specification is called out.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread — one of the most common coarse-thread sizes in trade fastener work\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inch length under head with partial threading for proper clamping in bolted joints\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction for medium-strength fastening requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in indoor and semi-exposed installations\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for consistent fit across replacement applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC hex head cap screw per ASME B18.2.1, suitable for any application specifying a Grade 5 steel partially threaded hex cap screw in that thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard hex wrench or socket set sized for 5\/16-inch hex cap screws. De-energize and isolate any equipment before replacing or adding fasteners to electrical enclosures or mechanical assemblies. Do not exceed the torque capacity appropriate for Grade 5 fasteners in the mating material — consult the equipment manufacturer's documentation when torque specifications are required. Ensure the mating threads are clean and free of debris before installation.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensional Standard\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: D30032\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691174461746,"sku":"D30032","price":35.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f8aeb981817e67e09adc7102a999578.jpg?v=1788281076","url":"https:\/\/voomisupply.com\/products\/value-collection-d30032-hex-head-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
