Metric stainless steel cup point set screws in A1, A2 and A4 are used where a secure grip on the mating component is required in applications exposed to corrosive environments. 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 essential. The range includes metric stainless steel cup point set screws manufactured according to ISO 4029 / DIN 916 in A1, A2 and A4 stainless steel grades. Typical applications include machinery, food processing equipment, marine environments, process industries and other installations where corrosion resistance and secure fastening are required.
