Manufactured from Grade 8 alloy steel, this fully threaded fastener delivers high tensile strength and reliable holding power under load. The 3\/8-16 UNC thread and 2-1\/2 inch overall length make it suited for deeper engagement applications. Drive is a 3\/16 inch internal hex (Allen), accepting a standard hex key. It meets ASME\/ANSI B18.3 and ASTM F912 standards, confirming dimensional and material compliance. Machinists, millwrights, and maintenance technicians commonly install these fasteners in production and field service settings.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used in mechanical drive assemblies where a rotating component such as a pulley, sprocket, gear, or shaft collar must be locked to a shaft. The cup point bites into the shaft surface to resist rotational and axial movement without requiring a through-hole. Typical applications include conveyor systems, pump shafts, HVAC blower wheel hubs, and general industrial machinery. The fractional inch UNC thread form is standard across North American mechanical hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eCup point geometry bites into shaft surface for strong anti-rotation hold\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread provides broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex drive accepts common Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch overall length suits deep-engagement or thick-collar applications\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or service fastener for any mechanical assembly using a 3\/8-16 UNC tapped set screw hole requiring a cup point, Grade 8 alloy steel fastener per ASME\/ANSI B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 3\/16 inch hex key or Allen driver. De-energize and lock out all equipment before accessing shaft assemblies. Thread the set screw into the tapped hole by hand to avoid cross-threading, then tighten with the appropriate hex key.
