What Is a Grub Screw?
A grub screw is also called a set screw. The term grub screw is derived from the word grub (beetle larva), meaning a screw that looks like a caterpillar. There are many other names for a grub screw, but a grub screw refers to a bolt with threads.
A bolt is a type of screw with a helical groove and generally refers to a male thread with a non-pointed tip larger than 8 mm. There are a wide variety of types of grub screw, which are defined by JIS standards.
Uses of Grub Screws
Bolts are used to fasten members together, but grub screws are often used in more specific applications for strength, aesthetic reasons, and security.
Some have a special hexagonal hole at the equivalent of a screw thread, which can only be rotated by a special tool. In other words, they are used in areas where security needs to be enhanced, such as vending machines and public restroom partitions, so that ordinary consumers cannot easily dismantle them.
Also, due to their structure of, they can be tightened with more torque than ordinary screws, and are superior in terms of fixing strength.
Principle of Grub Screws
The most significant feature of grub screws is the head added to the bolt.
Usually, the head is smaller than the diameter of the bolt and can be rotated with a flat-blade screwdriver or a roundhead. By fitting the head into the concave thrust pad, which is provided in pairs as a set, the torque force with a larger tip can maintain a stable clamping force.
The choice of head part is also an important feature in mechanical systems such as gears and pulleys, where metal surfaces rub against each other and the machine is not interrupted by the protruding heads of bolts and screws.
Grub screws are often made of steel or stainless steel, and many of them have their corrosion resistance superior to that of screws because the material that covers the entire screw is not exposed at the edges, as is usually the case with screws. However, care must be taken in handling them because if they corrode in certain areas or if the head is badly deformed by, for example, a screwdriver, the grub screw itself cannot be removed.
The official name for club screws is "hexagon socket set screw" or "set screw with mortise".
