Ketan Allen grub screws, also known as socket set screws, are a type of fastener that are commonly used in mechanical and industrial applications. They consist of a cylindrical shaft with a hexagonal recessed head, which is designed to be tightened or loosened using an Allen key or hex key. Unlike standard bolts and screws, grub screws do not have a head and are designed to be screwed into a threaded hole or shaft. They are commonly used to secure one object to another or to prevent a rotating part from moving. Ketan Allen grub screws are available in a variety of sizes, materials, and finishes to suit different applications and environments. They are commonly used in machinery, automotive, and construction applications, as well as in consumer products and DIY projects.
