It features a 1\/2-13 UNC thread size, a 1-3\/4 inch length under head, and is fully threaded from head to tip. The drive is a 3\/8 inch hex socket, compatible with standard hex keys and socket drivers. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this fastener meets ASME B18.3 and ASTM F837 standards. It is suited for maintenance, mechanical assembly, and equipment fabrication tasks across industrial and trade environments.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in mechanical assemblies, structural fastening, and equipment installations where a flush or low-profile head is required. The hex socket drive allows installation in tight clearance areas where a wrench cannot access a hex head. The stainless steel construction makes it appropriate for wet, corrosive, or food-adjacent environments. It is commonly installed by millwrights, pipefitters, HVAC technicians, and general mechanical contractors during equipment assembly or field repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread size for broad hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inch length under head, fully threaded\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch hex socket drive for use with standard Allen keys or socket drivers\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no added coating to interfere with thread fit\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.3 and ASTM F837 fastener 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 requiring a fully threaded, socket-drive cap screw conforming to ASME B18.3 dimensions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a calibrated torque wrench using a 3\/8 inch hex bit to avoid rounding the drive socket. De-energize or depressurize any equipment before fastener replacement or assembly work. When installing stainless steel fasteners into stainless threaded holes, apply an anti-seize compound to prevent galling. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.\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: 1-3\/4 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: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 18-8 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3, ASTM F837\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: 78118\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51751002145074,"sku":"78118","price":4114.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a2a0009891924a2ca223b5da382b3_215c4e17-56c0-470a-b1ff-07a23bbce46e.jpg?v=1788921084","url":"https:\/\/voomisupply.com\/products\/holo-krome-78118-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
