Product Information

Although slotted varieties are sold for use with standard flat-head screwdrivers, they’re less common than hex, Torx or Allen internal-wrenching drives, because slotted varieties are inherently less robust and more easily deformed during insertion under high torque forces. Because grub screws very often feature a recessed hole or slot at one end for a hex drive, Allen wrench or flat-head screwdriver - as opposed to a traditional head - they can be awkward to get sufficient purchase on for easy removal.

Conical point (cone point) - This is used when the thread part has insufficient thickness, and the lateral force is small.As stated in the section above, the most common uses for grub screws are to join or clamp one object or component tightly against another, but in specific scenarios where the use of a more traditional nut and bolt combination isn’t ideal for various reasons.

Similarly, an M5 x 150mm set screw will be 5mm in diameter across its threaded section, and 150mm long from head to end.Dog point - This type of set screw is used where the threaded part has sufficient thickness, and the lateral force is large. Socket Head Drive Grub Screws are headless with recessed drive ports into which you can insert a tool such as a hexagonal Allen key. One potential downside of flush-set grub screws, however, is that they can be quite difficult to remove once driven with full force to sit flush with or countersunk into the surface of the workpiece, especially if they do become corroded or the drive slot is damaged due to excessive torque going in.

Because they’re fully threaded and designed to be driven into an existing tapped hole or socket - rather than driven into the surface, creating a new hole - they’re commonly considered a type of bolt, albeit with a few key differences.Typical examples of uses for grub screws might include any situation where one object or component needs to clamp to another tightly via friction, but where protruding parts of the fastener would interfere with smooth functioning of the items in question. Grub screws are commonly found in automotive, construction, woodworking or in fact anywhere a strong, reliable and flush fastener is required. Instead, they’re usually threaded right to the top, and are the same diameter all the way along their length, meaning that the grub screw can be fully driven into its hole to sit flush with (or even countersunk into, depending on the application) the workpiece.
