In the vast universe of fasteners, the cone point set screw is a small but mighty hero. Often overlooked in favor of more well-known counterparts like the flathead or Phillips screws, the cone point set screw boasts unique qualities that make it indispensable in a variety of applications. In this article, we will delve into the world of cone point set screws, shedding light on their design, uses, and answering frequently asked questions.

What is a Cone Point Set Screw?

A cone point set screw, also known as a cone point grub screw, is a specialized type of screw designed for a specific purpose: to secure an object or component within a hole or on a shaft. What sets this screw apart is its conical or pointed tip, which creates a precise point of contact when it is tightened. This feature enables it to grip surfaces effectively, even on uneven or inclined surfaces.

The Anatomy of a Cone Point Set Screw

Understanding the anatomy of a cone point set screw is essential for appreciating its unique characteristics:

  • Head: These screws typically have a socket head, which requires an Allen wrench or hex key for installation. The head can come in various shapes, including cylindrical, flat, or countersunk.
  • Thread: The thread is the helical groove along the length of the screw that allows it to be threaded into a corresponding hole or onto a shaft.
  • Cone Point: The cone point, as the name suggests, is the conical tip of the screw. This is the key feature that distinguishes it from other screws.

Applications of Cone Point Set Screws

Cone point set screws find their utility in a wide range of applications, thanks to their unique design. Some common uses include:

  • Positioning Components: They are often used to secure gears, pulleys, and collars in place, ensuring proper alignment on shafts.
  • Locking Fasteners: Cone point set screws can be used to lock other fasteners, such as nuts or bolts, in position.
  • Micromechanics: In precision instruments and devices, these screws are used to secure delicate components without causing damage.
  • Electronics: They are employed to hold printed circuit boards and other electronic components securely in place.

FAQ About Cone Point Set Screws

Let’s address some of the frequently asked questions regarding cone point set screws:

Q1: Are cone point set screws suitable for permanent or temporary fastening?

A1: Cone point set screws are typically used for temporary fastening. They provide a strong grip but can be easily removed when needed.

Q2: What materials are cone point set screws made from?

A2: These screws are available in various materials, including stainless steel, alloy steel, and brass, to suit different environmental conditions and requirements.

Q3: How do you measure the size of a cone point set screw?

A3: The size is typically described by its diameter (e.g., M3) and length (e.g., 10mm).

Q4: Can cone point set screws be used for heavy-duty applications?

A4: They are not generally recommended for heavy-duty applications, as they are primarily designed for precise positioning and delicate components.

Q5: How is a cone point set screw installed and removed?

A5: They are installed using an Allen wrench or hex key, and removal is typically as straightforward as loosening the screw.


Cone point set screws may be small, but their impact in various applications is significant. These specialized screws offer precision and reliability, making them an invaluable addition to the world of fasteners. Whether you are working on a delicate piece of machinery or a precision electronic device, consider the unique benefits of cone point set screws for your fastening needs.
