Manufactured from Grade 8 alloy steel, it delivers high tensile strength and resistance to loosening under vibration and load. The cone point digs into or seats against a mating surface, creating a firm, concentrated hold. The 5\/32-inch hex drive accepts a standard hex key for installation and removal. At 5\/16-18 UNC threading and 3\/4-inch overall length, this fastener suits a wide range of industrial and trade applications where a reliable, recessed set screw is required.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used in collars, hubs, pulleys, shafts, and similar mechanical components found in HVAC equipment, pump assemblies, fan drives, and general industrial machinery. The cone point style is particularly effective when permanent or semi-permanent shaft positioning is needed, as the point creates an indent in the mating material for positive registration. Installation is straightforward and does not require access to the end of the fastener, making it well suited for flush or recessed applications. Sold individually per package, with a minimum order quantity of 100 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high strength and hardness\u003c\/li\u003e\n  \u003cli\u003eCone point geometry for positive shaft or surface engagement\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch overall length suits medium-depth engagement applications\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex drive accommodates standard hex keys and L-wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or stock set screw for any assembly requiring a 5\/16-18 UNC cone point set screw with a 5\/32-inch hex drive, conforming to ASME\/ANSI B18.3 and ASTM F912 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5\/32-inch hex key or L-wrench. Ensure the tapped hole is clean and free of debris before threading the screw. De-energize and lock out any equipment before servicing rotating components such as shafts, pulleys, or hubs. Do not overtighten, as cone point set screws can permanently deform softer shaft materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3\/4 inches\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\u003eDrive Size\u003c\/strong\u003e: 5\/32 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\u003eThread Standard\u003c\/strong\u003e: UNC\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\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: 121154PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723976606002,"sku":"121154PR","price":6067.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff734a4afe9837bbda722592bd427b7d_d97b3506-80f3-4e3c-b2de-f18043105373.jpg?v=1788610947","url":"https:\/\/voomisupply.com\/products\/value-collection-121154pr-set-screw-5-16-18-x-3-4-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
