It measures 5\/16-18 UNC thread with a 2-1\/2 inch length under the head. Manufactured from Grade 2 steel with a bright uncoated finish, this fastener is suited for low- to medium-strength clamping applications where corrosion resistance is not a primary requirement. Installation is performed with a standard hex wrench or socket. This screw follows inch-system dimensions and UNC thread standards, making it straightforward to source and replace in the field.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in a wide range of light-duty to moderate-duty assemblies including equipment panels, brackets, mechanical housings, and structural supports in HVAC, plumbing, electrical, and general trade environments. The partially threaded shank provides a smooth bearing surface on the unthreaded portion, which is useful when clamping two members together without thread engagement through the full grip length. It is appropriate for indoor or dry-environment applications given the uncoated steel finish.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread for compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch length under head with partial threading for controlled clamping grip\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate strength for general-purpose fastening\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for dry or protected indoor environments\u003c\/li\u003e\n  \u003cli\u003eHex drive head accepts standard sockets and wrenches for fast installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNC hex head cap screw for use in any application requiring a 5\/16-18 threaded fastener with a 2-1\/2 inch grip length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a properly sized socket or open-end wrench rated for the fastener drive size. Ensure the mating tapped hole or nut matches the 5\/16-18 UNC thread specification before installation. Do not exceed the torque rating appropriate for Grade 2 steel at this thread size, and avoid using impact tools at full power to prevent thread damage. Because this fastener is uncoated steel, apply anti-seize or thread lubricant as needed based on environmental conditions.\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: 2-1\/2 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\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: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 402066PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693371195698,"sku":"402066PR","price":2234.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5464d725471cee139777aad63bfc30d3.jpg?v=1788311357","url":"https:\/\/voomisupply.com\/products\/value-collection-402066pr-hex-head-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
