Sized at 1\/2-13 UNC thread with an overall length of 1-1\/4 inches, it is driven by a 1\/4-inch hex key and manufactured from Grade 8 alloy steel for high tensile strength under load. Conforming to ASME\/ANSI B18.3 and ASTM F912 standards, this set screw suits demanding industrial and mechanical applications. Machinists, millwrights, and maintenance technicians regularly install this fastener type during shaft-to-hub assemblies, set collar installations, and similar mechanical connections.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in mechanical power transmission components such as shaft collars, shaft couplings, pulleys, sprockets, and gear hubs where the half dog point engages a mating hole or recess in the shaft to prevent rotation or axial movement. The half dog point profile provides a positive seat in the shaft recess while minimizing surface damage compared to a full dog or cup point. It is commonly found in light industrial machinery, conveyor systems, and general fabrication environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHalf dog point engages shaft recesses for secure, repeatable positioning\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread for wide compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex drive accepts standard Allen or hex key tooling\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eOverall length measured as fractional inch per standard convention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC set screw for use in any tapped 1\/2-13 threaded hole requiring a half dog point fastener 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 by machinists or maintenance technicians using a 1\/4-inch hex key or Allen wrench. Ensure the mating shaft recess or flat is properly aligned with the screw axis before tightening. Deburr tapped holes and clean threads before installation to achieve consistent seating.
