Metric Socket Set Screws (also called grub screws) are headless fasteners designed to secure one object within another, such as fixing a gear, pulley, or knob to a shaft. Tightened with an internal hex drive, they sit flush or below the surface for a clean, snag-free fit.

Available in sizes from M2 to M12, Monster Bolts carries set screws in 12.9 alloy steel (black oxide or zinc) and stainless steel for corrosion resistance.

Common Point Styles

Cup Point: The most widely used style, with a concave tip that bites into the mating surface for strong holding power.
Knurled Point: A serrated tip that locks into softer materials, resisting loosening under vibration.
