Sized at 1\/2-13 UNC with a 1-5\/8-inch length under head, this screw is fully threaded and accepts a 3\/8-inch hex drive. Constructed from alloy steel with a black oxide coating, it provides corrosion resistance and reduces light reflection in service environments. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding structural and mechanical assemblies where torque load and material strength are critical.\u003c\/p\u003e\n\u003cp\u003eThis socket cap screw is used in a wide range of trade and industrial applications including HVAC equipment mounting, mechanical assemblies, pump and motor housings, structural brackets, and general fabrication work. The 1\/2-13 UNC thread is a coarse-thread standard commonly found in steel assemblies requiring reliable clamping force. The black oxide finish suits both indoor and moderate-exposure environments. Installation is typically performed by millwrights, pipefitters, HVAC technicians, or general tradespeople using standard hex keys or socket drive tools.\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 assemblies\u003c\/li\u003e\n  \u003cli\u003e1-5\/8-inch length under head, fully threaded\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive for use with standard hex keys or socket wrenches\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and a low-glare finish\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional 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 use in any application calling for an ASME\/ANSI B18.3 or ASTM A574 compliant fastener of this thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed using a properly sized 3\/8-inch hex key or socket drive tool to avoid stripping the socket head. Ensure mating threads are clean and free of debris before driving. De-energize or lock out any equipment before replacing or installing fasteners in mechanical assemblies. Follow applicable industry torque guidelines for 1\/2-13 UNC alloy steel fasteners as specified by the equipment manufacturer or relevant standards.\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: 1-5\/8 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: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\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\u003eWeight\u003c\/strong\u003e: 0.1 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: 581543PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716958880050,"sku":"581543PS","price":2337.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5856af2e77f8db83235fa29f8533ebc.jpg?v=1788534041","url":"https:\/\/voomisupply.com\/products\/value-collection-581543ps-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
