A cone point grub screw is ideal for use with a slotted spindle where the point will locate in the slot which will in turn put pressure to spread or widen the slot ensuring a tight fit for the spindle in the handle.

A grub screw is commonly used as a locking device, particularly on custom modified Gears, Taper Locking Bushes, Pulleys or Adjusting Rings. The grub screw is tightened perpendicular to a shaft to restrict the movement of a connected component.

Grub Screws are used to connect two objects by threading into one and applying tension to the other. The high level of torque this produces results in a strong yet inconspicuous fastening. The Cup Point on this Grub Screw has a thin edge that digs into the fastened surface to provide a secure hold.
