Set Screws are blind (headless) fasteners with an internal hex drive. It is this drive style that classifies stainless steel screws in this selection as set screws, which are driven by a hex bit or Allen wrench. Grub Screws are used in a tapped hole and tightened to hold an exterior object in place within or against another object, via friction between the point or end of the screw and the material that is being fastened.

Set Screws are also often used in applications where a flush installation and the look of the final assembly are important, such as furniture assembly. Socket Set Screws will run flush with the installation surface. They are often plugged after installation for a hidden fastener look. These qualities are what make set screws commonly used in applications where a flat surface is important, such as handles, grips, surfboard fins, and furniture or machine assembly. Because a flush surface is important on complex machines, Set Screws are also commonly used in gears, pulleys, and wheel in machines with moving parts.

The set screw passes through a threaded hole in the outer object and is tightened against the inner object to prevent it from moving relative to the outer object. It exerts compression or clamping force through the bottom tip that projects through the hole.

Available with points including Cup Point, Cone Point, Flat Point and Dog Point.

Cone Point

They are used for permanent location of parts. Deep penetration on tightening gives highest axial and holding power.

The pointed tip can either located into a machined depression or it can make and indentation into a softer material. It offers better holding power and increased point pressure.

In material over Rockwell C15 point is spotted to half its length to develop shear strength across point. It is also used for pivots and fine adjustment.

Available in ISO 4027 or DIN 914
