It is driven with a 1\/8 inch hex key and is built to ASME\/ANSI B18.3 and ASTM F912 standards. Half dog point set screws are used to lock components onto shafts while still allowing controlled axial movement or positioning. The Grade 8 alloy steel construction delivers high tensile and torsional strength suited for demanding mechanical assemblies. This fastener is installed by machinists, maintenance technicians, and industrial mechanics across a wide range of equipment applications.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in shaft collars, couplings, pulleys, sprockets, and similar rotating or sliding mechanical components where a half dog point is specified. The half dog point engages a mating hole or detent in the shaft to resist rotation while still permitting limited axial travel. It is commonly found in light industrial machinery, conveyor systems, and precision mechanical assemblies requiring repeatable positioning. Thread size is 1\/4-20 UNC with an overall length of 1\/2 inch.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHalf dog point design for shaft engagement with controlled axial movement\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel for high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch hex drive for precise torque application with standard hex keys\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1\/2 inch; fractional inch measurement type\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service set screw for mechanical assemblies specifying a 1\/4-20 UNC half dog point fastener per ASME\/ANSI B18.3 and ASTM F912.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a 1\/8 inch hex key. Always de-energize and lock out the equipment before accessing any shaft or rotating assembly. Verify the mating shaft has an appropriate detent or hole to accept the half dog point before tightening.
