Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this fastener measures 2-1\/4 inches under the head and features partial threading along its shank. The 3\/8-16 thread designation indicates a 3\/8-inch nominal diameter with 16 threads per inch, making it a standard coarse-thread inch-series fastener. A 9\/16-inch hex key size is required for installation. This screw is sold individually, with a minimum order quantity of 100 pieces.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for light-duty structural and mechanical assembly in residential and commercial construction, HVAC equipment mounting, plumbing fixture installation, electrical enclosure assembly, and general maintenance work. Its partial threading allows it to clamp two materials together with a smooth shank bearing surface between the head and threaded section, which is useful in applications where the fastener passes through a clearance hole before engaging a tapped hole or nut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC coarse-thread designation for broad compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e2-1\/4-inch length under head with partial threading for clearance-hole-through applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate tensile strength for light-duty general fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic corrosion resistance in dry or mildly humid environments\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch hex drive size compatible with standard open-end, box-end, and socket wrenches\u003c\/li\u003e\n  \u003cli\u003eInch-system measurement, UNC thread standard, sold per piece with 100-piece minimum order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8-16 UNC inch-series tapped holes and compatible with any standard 3\/8-16 hex nut or coupling nut meeting UNC thread specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 9\/16-inch wrench or socket driver. Power down or de-energize any equipment before accessing fastener locations on electrical or mechanical enclosures. Ensure mating threads are clean and free of debris before driving the screw. Do not overtighten Grade 2 fasteners in tapped aluminum or cast iron, as the lower tensile rating of Grade 2 steel increases the risk of thread stripping or fastener failure under excessive torque.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-1\/4 inches\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 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\u003eThread Standard\u003c\/strong\u003e: UNC\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: 0.05 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: 403116PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715474489650,"sku":"403116PR","price":5291.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c528cfdd5dfd84eb1f43d9f0af8a4589.jpg?v=1788514460","url":"https:\/\/voomisupply.com\/products\/value-collection-403116pr-hex-head-cap-screw-3-8-16-x-2-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
