Set Screws from Fabory: Headless Connections with Flush Appearance

Set screws, also known as grub screws, are types of fasteners typically headless or with just a socket head, threaded along their entire length to sit flush with or below the surface of the workpiece after installation. Unlike other screws, set screws are designed to be tightened into a material or part to exert compression or clamping force rather than securing objects through a threaded hole. They are primarily used for securing an object within or against another object, making them ideal for applications where space is limited or a smooth surface is necessary. Common uses include securing collars, pulleys, and gears to shafts in mechanical applications, with the screw exerting a holding force through a bottom tip that can be pointed, flat, cup-shaped, or another designed shape for better grip.

When selecting set screws, several important details must be considered. Material and grade vary based on application needs, ranging from steel and stainless steel to brass and alloy steel, each offering different levels of strength and corrosion resistance. The point style, such as flat, cone, cup, or dog point, determines the pressure distribution and grip type. Proper sizing and length are crucial for holding power and application suitability. Drive types commonly include hexagon socket or slotted drives. Adhering to standards like DIN, ISO, or ASME ensures compatibility and reliability.
