Set Screws (Grub Screws) – Compact Fastening with Maximum Grip
Product Description
Set Screws, also known as Grub Screws, are headless threaded fasteners designed to hold one object within or against another. These screws are installed entirely below the surface of the material and commonly used in mechanical assemblies, pulleys, shafts, and rotating parts where a flush fit is required.
At SM Fasteners, we manufacture set screws in accordance with DIN and ISO standards, using premium alloy and stainless steels, heat-treated for hardness and durability. Available in multiple point types like flat point, cone point, cup point, dog point, and knurled cup, these screws offer excellent torque holding capabilities.
Applications
Set screws are a critical component in applications where traditional bolts or screws with heads are impractical:
Gear Fixation on Shafts
Pulleys and Couplings
Electronics and Circuit Assembly
Tooling and Dies
Automotive Internal Mechanisms
Machinery and Rotational Parts
Robotics and Precision Equipment
