Grub Screws

Grub Screw Types
Grub Screw – Plain Cup Point
– Used to fasten shaft collars, gears or knobs to shafts.
– Used against hardened surfaces or when frequent adjustments are needed and where no locking point is required.
– Cup point grub screws are the most commonly used of the various styles. The tip is slightly concave.
Grub Screw – Knurled Cup Point
– Use where vibration may be a problem. Knurls lock onto seating material and prevents screw from loosening.
Grub Screw – Cone Point
– For permanent location of parts. Deep penetration of point gives the highest holding power. Cone point grub screws have a tip that tapers to a point. We stock metric sizes from M3 to M8.
Grub Screw – Dog Point
– Used for permanent location of one part to another. Point is often set into a drilled hole. May sometimes take the place of a dowel pin. Dog point grub screws are used where a positive engagement into a shaft slot (for example) is required. The tip is cylindrical and dimensions are shown on the listing page.
Grub Screw – Flat Point
– Used when parts must frequently be reset. Causes very little or no damage to the part it seats against.
