Sized at 5\/8-18 UNF with a 1-1\/2 inch length under head and fully threaded shank, this fastener is manufactured from alloy steel and finished with a black oxide coating for corrosion resistance in dry and mildly corrosive environments. The 1\/2 inch hex drive accepts standard hex keys and socket drivers. It meets ASME B18.3 and ASTM A574 standards, confirming its dimensional accuracy and mechanical strength. Licensed tradespeople and maintenance professionals use this screw in structural, mechanical, and equipment assembly work where controlled torque and a low-profile head are required.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for industrial, commercial, and trade applications including HVAC equipment assembly, pump and motor mounting, electrical enclosure hardware, and general mechanical maintenance. The fine 18-thread-per-inch pitch provides precise clamping force and resistance to loosening under vibration. It is sold individually, making it practical for replacement and repair work where single-piece quantities are needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF fine thread for precise torque control and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch length under head, fully threaded shank\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces glare\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch internal hex drive compatible with standard hex keys and socket tools\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standards\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 compatible with any 5\/8-18 UNF tapped hole application requiring an ASTM A574 alloy steel fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/2 inch hex key or Allen socket driver torqued to the fastener manufacturer or equipment OEM specification. De-energize and lock out any equipment before replacing or installing fasteners in mechanical assemblies. Do not mix inch and metric thread fasteners in the same assembly. Inspect threads for damage before installation and use thread-locking compound where vibration loosening is a concern.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\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: 1\/2 inch\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 73150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51742317314354,"sku":"73150","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7c3eda723153b5ea615a08bcf796945.jpg?v=1788836714","url":"https:\/\/voomisupply.com\/products\/holo-krome-73150-hex-socket-cap-screw-5-8-18-unf-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
