What are Set Screws

Set screws, also known as grub screws, are threaded fasteners designed without a head and commonly feature a hex socket or slotted drive on one end. These screws are used to secure an object within or against another object, usually without the need for a nut.

Characteristics of Set Screws:

1. Headless Design: Set screws lack a traditional head, providing a flush and neat appearance when installed.

2. Threaded Entirety: They have threads along the entire length, allowing them to be fully threaded into a tapped hole or into a material.

3. Drive Types: Set screws typically feature a hex socket (Allen) or slotted drive on one end, allowing for tightening using a corresponding tool.

4. Material Options: Available in various materials including steel, stainless steel, brass, and alloy steel to suit different applications and environments.

Types of Set Screws:

1. Cup Point Set Screws: These have a rounded or cup-shaped indentation at the end to provide a firm grip without damaging the mating surface.

2. Cone Point Set Screws: The end of these screws comes to a sharp conical point, offering high holding power by embedding into the mating material.

3. Flat Point Set Screws: Featuring a flat or slightly rounded end, these screws apply force without leaving marks on the surface.

4. Oval Point Set Screws: Have an oval-shaped indentation at the end, providing better alignment and reduced marring of surfaces.

5. Half Dog Point Set Screws: These screws feature a partial indentation or point, offering a balance between holding strength and surface contact.

Applications of Set Screws:

– Shaft Fixing: Used to secure gears, pulleys, and couplings onto shafts by penetrating into the shaft’s surface.

– Alignment: Utilized in machinery and equipment to align components or act as locator pins.

– Fastening Components: Securely attach knobs, handles, or collars onto shafts or rods.

– Electronics: Used in electronic devices to secure parts within housings or mounting brackets.

Materials of set screws
