Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to loosening under vibration and load. The cone point geometry bites into the mating surface for a firm, non-slip hold. It accepts a 1\/4-inch hex key for installation and complies with ASME\/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, maintenance mechanics, and industrial tradespeople rely on this style of set screw in precision assembly and mechanical positioning work.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for use in manufacturing, industrial maintenance, and mechanical assembly environments. Common applications include securing pulleys, gears, collars, and couplings to shafts where a permanent or semi-permanent hold is required. The cone point is especially effective on soft shafts where point penetration provides maximum torque resistance. The 1\/2-13 UNC thread size and 5\/8-inch overall length make it appropriate for medium-duty shaft locking tasks across a range of industrial equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCone point geometry for positive shaft penetration and high holding strength\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction for elevated tensile and torsional strength\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC thread for compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003e5\/8-inch overall length measured as total fastener length\u003c\/li\u003e\n\u003cli\u003e1\/4-inch hex drive accepts standard hex keys and Allen wrenches\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC threaded set screw for use in any 1\/2-13 tapped hole requiring a cone point fastener per ASME\/ANSI B18.3 specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance mechanics using a 1\/4-inch hex key or Allen wrench. Ensure the receiving hole is properly tapped to 1\/2-13 UNC before installation. De-energize and lock out all equipment before servicing any assembly containing set screws. Avoid overtightening, which can damage the shaft surface or strip the tapped hole.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5\/8 inches (overall length)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/4 inches (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F912\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\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: 121193PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723853398322,"sku":"121193PR","price":1695.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff734a4afe9837bbda722592bd427b7d_495dabfc-ceab-4f69-876d-b2c9137e0416.jpg?v=1788608779","url":"https:\/\/voomisupply.com\/products\/value-collection-121193pr-set-screw-1-2-13-x-5-8-in-cone-point","provider":"Voomi Supply","version":"1.0","type":"link"}
