Grub screws are fully threaded fasteners without an external head, designed to be screwed flush or below the surface of a mating part. This design ensures that the screw does not protrude, making it ideal for applications where a smooth, unobtrusive finish is required. They exert pressure on a mating surface to prevent movement or secure components such as shafts, gears, or collars.

Materials:

Stainless Steel: Offers excellent corrosion resistance and is suitable for marine, chemical, and food processing environments.

Carbon Steel: Provides high strength and durability, often coated or plated for corrosion resistance.

Alloy Steel: Used where higher mechanical strength is necessary.

Brass: Used for low-strength applications, offering good corrosion resistance and electrical conductivity.

Drive Types:

Hex Socket (Allen): The most common, allowing strong torque application and easy installation with an Allen key.

Slotted: Traditional drive type, less common due to limited torque capability.
