At 1 inch overall length, it is driven by a 1\/4-inch hex key and conforms to ASME\/ANSI B18.3 and ASTM F880 standards. Cup point set screws are used to lock shafts, collars, pulleys, and similar rotating components in place by biting into the mating surface. Grade A2 stainless construction provides corrosion resistance suitable for wet, outdoor, or chemically exposed environments. This fastener is specified and installed by machinists, millwrights, pipefitters, HVAC technicians, and general maintenance trades.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for shaft-to-hub locking applications across a wide range of mechanical assemblies including motor shafts, fan hubs, shaft collars, couplings, and valve stems. The cup point geometry creates a defined indent in the mating shaft surface, providing positive rotational and axial resistance. It is appropriate for both light industrial and general mechanical service where stainless steel corrosion resistance is required over standard alloy steel alternatives.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF thread for fine-thread engagement and precise torque control\u003c\/li\u003e\n  \u003cli\u003e1 inch overall length providing adequate thread engagement depth\u003c\/li\u003e\n  \u003cli\u003eCup point geometry bites into shaft surface for positive holding force\u003c\/li\u003e\n  \u003cli\u003eAustenitic Grade A2 stainless steel resists corrosion in wet and chemical environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex drive conforms to ASME\/ANSI B18.3 and ASTM F880 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 1\/2-20 UNF cup point set screw with a 1\/4-inch hex drive.
