Stainless Steel Oval Point Grub Screw - Grade 202, 304, 316, A2, A2-70
Oval Point Grub Screw, also known as set screws with oval ends, are a type of headless screw used to secure one object within or against another without protruding above the surface. The defining feature is the oval-shaped tip, which provides a gentler clamping action compared to other point types, reducing the risk of surface damage.

Oval point grub screw, also referred to as oval point set screws, have a rounded, oval-shaped tip that minimizes surface damage when fastened. They are commonly used to hold components in place by generating a clamping force, particularly in applications where rotating parts such as gears, pulleys, and collars are involved. Compared to flat or cup point screws, the oval point makes it easier to make adjustments without causing harm to the mating surface.
