Premium M2-M24 Set Screws: Precision Locking for Industrial Assemblies

Our M2-M24 Set Screws, widely known as Grub Screws, are essential for applications requiring a flush-fit, headless fastening solution. Engineered to secure an object within or against another, these headless set screws are primarily used to lock gears, pulleys, and collars onto shafts. Manufactured strictly to DIN 913, 914, 915, and 916 standards, our fasteners provide the high torque and reliability needed for high-speed rotating machinery.

As a leading set screw factory, we offer a full spectrum of materials, ranging from High-Tensile 12.9 Alloy Steel for maximum clamping force to 316 Stainless Steel for superior corrosion resistance in medical and marine equipment.

Key Advantages of Our DIN 913-916 Series

  • Headless Flush Design: Allows the screw to be fully submerged in the threaded hole, saving space and preventing interference in compact assemblies.
  • Internal Hex Drive: Deep, precision-cut sockets allow for the application of significant torque using standard Allen keys, ensuring a secure lock.
  • Versatile Point Options: From Cup Point (DIN 916) for maximum grip to Cone Point (DIN 914) for permanent positioning.
  • Industrial Strength: Our 12.9 grade alloy steel screws undergo rigorous heat treatment to achieve exceptional hardness and tensile strength.

  • Robotics & CNC: Used in stepper motors and precision couplings for accurate motion control.
  • Consumer Electronics: M2 and M3 sizes are used in hardware and instrumentation for flush fastening.
  • Power Transmission: Locking pulleys, sprockets, and bearings onto rotating shafts.

Set Screw Frequently Asked Questions

Q: Which point type should I use for a hardened shaft?
A: We recommend Cup Point (DIN 916) for general grip or Flat Point (DIN 913) if you want to avoid marking or damaging a precision-ground shaft.

Q: Do you offer M16+ sizes in Stainless Steel?
A: Yes, we specialize in large-diameter stainless steel grub screws for heavy-duty marine and chemical agitation equipment.
