Made from Grade 5 steel with a zinc-plated finish, this partially threaded fastener meets ASME B18.2.1 standards for dimensional accuracy and head geometry. The 3\/8-16 UNC thread pattern and 1-3\/4 inch length under head make it a common choice for structural and equipment mounting applications across residential and commercial trade work. Sold in a package of 25, it suits service techs and installers who need reliable hardware on hand for jobsite repairs or unit installations.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is used across a wide range of trade applications including HVAC equipment mounting, electrical enclosure assembly, plumbing bracket fastening, and general mechanical equipment repair. The partially threaded shank provides stronger clamping force in through-bolt applications compared to fully threaded designs, making it well suited for connecting flanged components or securing panels and frames. It is compatible with standard 3\/8-16 UNC nuts and tapped holes in steel and aluminum assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 5 steel construction provides reliable tensile strength for structural fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic corrosion resistance for indoor and protected outdoor installations\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves clamping performance in through-bolt configurations\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread standard ensures broad compatibility with standard nuts and tapped fittings\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for consistent head geometry and thread accuracy\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 25 reduces per-fastener cost and supports routine service stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC hex head cap screw for use in any application requiring an ASME B18.2.1-compliant partially threaded fastener in Grade 5 steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with the appropriate 9\/16 inch hex wrench or socket driver; do not substitute metric tooling on UNC fasteners. Apply torque in accordance with applicable Grade 5 fastener torque tables for the joint material being used. Ensure mating threads are clean and free of debris before assembly. Do not exceed the rated torque for Grade 5 steel at this thread size, as over-torquing can cause thread stripping or fastener failure.\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: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\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\u003ePackage Quantity\u003c\/strong\u003e: 25\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: MP30057\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694641086770,"sku":"MP30057","price":17.65,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9aea383b182ad51e4457dde3541b6954.jpg?v=1788326635","url":"https:\/\/voomisupply.com\/products\/value-collection-mp30057-hex-cap-screw-3-8-16-grade-5-zinc-25pk","provider":"Voomi Supply","version":"1.0","type":"link"}
