What are Types of Set Screws and Their Uses

Set screws may be small, but they play a crucial role in holding various components together. These unassuming fasteners offer versatility and reliability in a wide range of applications. In this article, we will explore the world of set screws, their types, and their diverse uses, shedding light on the importance of a well-curated set screw assortment.

What are the Set Screws?

Set screws, also known as grub screws, are threaded fasteners with no external head. Instead, they rely on their threaded body and tip to secure objects in place. These unthreaded gems come in a variety of types, each designed to cater to specific applications and demands.

What are Types of Set Screws and Their Uses?

Set screws come in various types, each designed for specific applications and requirements. The choice of set screw type depends on factors like the nature of the connection, the materials being fastened, and the intended use. Here are some common types of set screws and their typical uses:

Set Screw Type	Common Uses
Cup Point Set Screw	Securing objects without marring surfaces (e.g., pulleys, collars on shafts).
Flat Point Set Screw	Providing flush, surface-level connections (often used for aesthetics and alignment).
Cone Point Set Screw	Offering a strong, non-slip grip for precision applications (securing components on shafts).
Oval Point Set Screw	Balancing grip and aesthetics, suitable for applications where both functionality and appearance matter.
Half-Dog Point Set Screw	Allowing precise adjustment and alignment in machinery and tooling applications.
Nylon-Tip Set Screw	Providing a non-marring, vibration-resistant connection, commonly used in electronics and instrumentation.
Cone-Point Socket Set Screw	Enabling recessed fastening with a strong grip, used for securing knobs or handles to shafts.
Flat-Point Socket Set Screw	Achieving flush, low-profile fastening in various applications without compromising strength.
Cup-Point Socket Set Screw	Offering a powerful, recessed grip for strong, non-slip connections without surface damage.
