Metric stainless steel set screws in A1, A2 and A4 are used to secure, lock and position shafts, hubs, gears, pulleys and other machine components where corrosion resistance is required. The range includes both hex socket and slotted designs, depending on the applicable standard and application. Different point styles are available to suit specific requirements. Flat point screws minimize surface marking, cone point screws provide maximum holding power by penetrating the mating surface, dog point screws provide positive location in pre-drilled holes or slots, and cup point screws concentrate the clamping force onto a smaller contact area for a secure grip. This category includes metric stainless steel set screws for machinery, food processing equipment, marine environments, process industries and other applications where corrosion resistance and long service life are essential.
