Manufactured from Grade 5 steel with a zinc-plated finish, this fastener delivers reliable clamping force in both indoor and light outdoor environments where moderate corrosion resistance is required. The screw measures 4 inches in length under the head and features partial threading along the shank, conforming to ASME B18.2.1 dimensional standards. Sold in a pack of 10, this screw is a standard UNC-thread fastener suitable for use by HVAC technicians, pipefitters, electricians, and general maintenance personnel who need a reliable inch-series cap screw on the job.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is used across a wide range of trade and industrial applications including equipment mounting, panel assembly, bracket installation, and mechanical fastening in residential and light commercial settings. The 3\/8-16 UNC thread size is one of the most common inch-series thread standards, making it compatible with a broad range of tapped holes, nuts, and threaded inserts found in standard mechanical assemblies. The partially threaded shank provides a grip section that helps maintain joint alignment under load.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 5 steel construction provides adequate tensile strength for general mechanical fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers light corrosion resistance for indoor and semi-exposed installations\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows for precise clamping without full-thread engagement through the joint\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread standard ensures broad compatibility with standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for dimensional consistency and quality assurance\u003c\/li\u003e\n  \u003cli\u003eSold in a 10-pack to support common service and installation quantities\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw suitable for use with 3\/8-16 UNC tapped holes, nuts, and threaded inserts in general mechanical, HVAC, plumbing, and electrical equipment assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex wrench, socket, or open-end wrench sized for a 3\/8-inch hex head cap screw. De-energize and lock out all electrical equipment and relieve system pressure before fastening or unfastening hardware in pressurized or live systems. Do not exceed the torque capacity appropriate for Grade 5 steel fasteners at this thread size; consult applicable mechanical codes or equipment manufacturer guidelines for torque requirements. Inspect threads for damage before installation and ensure mating threads are clean and free of debris.\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: 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\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: MP30066\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702532440370,"sku":"MP30066","price":15.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b9e6da68026e3d134dc9e33467cc295.jpg?v=1788411833","url":"https:\/\/voomisupply.com\/products\/value-collection-mp30066-hex-head-cap-screw-3-8-16-x-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
