It features a 3\/8-16 UNC thread size with a 2-inch length under the head and accepts a 5\/16-inch hex drive. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance and reduced light reflection in service environments. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it a reliable choice for engineers, millwrights, and maintenance technicians who need a standardized, high-tensile socket cap screw.\u003c\/p\u003e\u003cp\u003eThis screw is suited for general industrial, manufacturing, and maintenance applications where a recessed drive fastener is required. Partial threading allows for improved clamping force in bolted joint assemblies. The black oxide alloy steel construction holds up in both indoor and light-duty outdoor environments. It is commonly used in machine component assembly, equipment mounting, fixture fabrication, and similar mechanical service work where a socket cap fastener is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC thread size with 2-inch length under head\u003c\/li\u003e\n\u003cli\u003ePartially threaded for improved clamping load in bolted joints\u003c\/li\u003e\n\u003cli\u003e5\/16-inch hex socket drive for standard Allen wrench or hex bit compatibility\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction with black oxide finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8-16 UNC hex socket cap screw suitable for use in any application calling for an ASME\/ANSI B18.3 compliant socket head cap screw of this thread size and length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed with a properly sized 5\/16-inch hex key or socket bit to avoid rounding the drive recess. Apply appropriate thread torque per the joint design specification for 3\/8-16 alloy steel fasteners. Ensure mating threads are clean and free of debris before installation. Always de-energize and lock out any equipment before accessing fasteners on powered machinery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partial\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\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\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 33638\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709711745330,"sku":"33638","price":35.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46493886debe6861ac955ce1e0604143.jpg?v=1788459441","url":"https:\/\/voomisupply.com\/products\/value-collection-33638-hex-socket-cap-screw-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
