Our Production Capabilities
Due to their lack of a head, Grub screws are often referred to as blind screws. We follow strict process control to ensure consistent quality and dimensional accuracy in every grub screw we produce. Fasteners India operates a modern manufacturing facility equipped with CNC turning machines, thread rolling units, heat treatment furnaces, and surface finishing systems.
What Are Grub Screws?
To make using allen keys easier, the screws feature an inbuilt hex drive. These are employed to bind two objects together or secure one object inside another. Grub screws, also known as set screws, are headless fasteners used to secure one object within or against another. They are commonly used to lock gears, pulleys, collars, and components onto shafts.

- Compact, headless design
