Product Description
M3 A2 Stainless Steel Slotted Cup Point Grub Screws
These M3 slotted grub screws are manufactured from corrosion-resistant A2 stainless steel and feature a cup point for secure clamping. Their headless, fully threaded design allows the screw to sit flush with or below the surface of the component.
Manufactured to the dimensional pattern associated with DIN 438 and the current ISO 7436 / BS EN ISO 7436 standard, these set screws have a standard M3 metric coarse thread with a 0.5mm pitch.
The cup point concentrates clamping pressure around its circular edge, helping the screw grip shafts, collars, pulleys, gears and other components. The straight slot allows installation and adjustment using a suitable flat-bladed screwdriver.
