M3 x 0.5 x 20 Mm Coarse Black Oxide Alloy Steel DIN 916 Cup Point Socket Head Set Screw
Item A85.3.20
Socket set screws also known as grub screws have no head and are typically tightened or loosened with a square or hex key. A slotted set screw can be adjusted with a screwdriver. Socket set screws prevent movement of a pulley or similar machine part relative to a shaft. A cup point set screw has a rounded tip that grips and resists deforming the shaft surface. A flat point screw provides more contact with the shaft.
