Steel UNC and UNF cup point set screws are used where a secure grip on the mating component is required for imperial-threaded equipment. The cup point concentrates the clamping force onto a smaller contact area, increasing the contact pressure and providing high resistance to rotation and axial movement. This makes cup point set screws a common choice for shafts, hubs, gears, pulleys and other machine components where reliable locking is important. The range includes steel UNC and UNF cup point set screws manufactured according to ANSI B18.3 for machinery, maintenance, power transmission systems and industrial equipment using imperial threaded components.
