It features a 1\/2-13 UNC thread and a 3\/8 inch hex drive socket for use with a hex key or Allen wrench. The screw is partially threaded with a length under head of 2-3\/4 inches, manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for applications where dimensional accuracy and tensile strength are critical requirements.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used across a broad range of industrial and mechanical service applications including machinery assembly, equipment mounting, and structural fastening where a recessed drive style is preferred. The 1\/2-13 UNC coarse thread pitch is well suited for general-purpose steel and iron assemblies. The black oxide finish is commonly specified in applications where mild corrosion protection and a low-glare appearance are acceptable. Installation is performed by maintenance technicians, millwrights, pipefitters, and general mechanical tradespeople working in commercial and industrial environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC coarse thread for reliable engagement in steel and iron tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch hex socket drive compatible with standard hex keys and torque tools\u003c\/li\u003e\n  \u003cli\u003e2-3\/4 inch length under head with partial threading\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength and durability\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 dimensional and strength standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC hex socket cap screw suitable for tapped holes conforming to ASME\/ANSI B18.3 specifications in general industrial and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 3\/8 inch hex key or socket drive torque tool. De-energize and lock out all equipment before fastener installation or removal per applicable OSHA lockout\/tagout procedures. Ensure the mating tapped hole is clean and free of debris before threading the screw. Do not use impact tools without a torque-limiting attachment, as alloy steel cap screws can be damaged by overtorque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-3\/4 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: 3\/8 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\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 33669\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695798059314,"sku":"33669","price":45.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a8694ccf466d7ad27cf3400ff2f0248.jpg?v=1788338307","url":"https:\/\/voomisupply.com\/products\/value-collection-33669-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
