Manufactured from alloy steel with a black oxide finish, this screw meets ASME B18.3 and ASTM A574 standards, making it suitable for precision mechanical assemblies and structural fastening in industrial and trade environments. The 5\/16-inch hex drive accepts a standard Allen-type key, allowing installation in confined spaces where a wrench or screwdriver cannot reach. Partial threading along the shank provides a smooth bearing surface for shear-load applications. This fastener is handled and installed by millwrights, pipefitters, HVAC technicians, and general mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for both light industrial and heavy mechanical assemblies requiring a fine-thread UNF specification. The 3\/8-24 UNF thread pitch offers finer engagement and greater tensile resistance compared to coarse-thread equivalents of the same diameter. The 5.5-inch length under head accommodates thicker stack-up applications such as equipment brackets, flanged assemblies, motor mounts, and structural hardware installations across commercial and industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF fine thread for high tensile strength and precise thread engagement\u003c\/li\u003e\n  \u003cli\u003e5.5-inch length under head suits thick-material and multi-layer fastening applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength socket screw requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports shear-load and close-tolerance bore applications\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive compatible with standard Allen keys and hex bit drivers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.3 hex socket cap screw suitable for equipment and assemblies specifying a 3\/8-24 UNF partially threaded fastener in alloy steel with black oxide finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or technician familiar with torque specifications for ASTM A574 alloy steel fasteners. De-energize and lock out all equipment before fastening work begins on powered assemblies. Use a properly sized 5\/16-inch hex key or socket bit to avoid rounding the drive. Apply thread lubricant or thread-locking compound only where specified by the equipment manufacturer's service documentation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 5\/16 inches\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: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 730001840\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51743888933170,"sku":"730001840","price":2038.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac0026dcfb83b395cce8f69fab5e216f.jpg?v=1788850823","url":"https:\/\/voomisupply.com\/products\/holo-krome-730001840-hex-socket-cap-screw-3-8-24-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
