Product Details

Our DIN 915 set screws are designed for reliability and precision. They are headless, fully threaded fasteners that function by being driven into a threaded hole until the dog point engages with a recess in the inner object, locking it securely in place.

• DIN 915 Standard with Dog Point: These screws are manufactured in compliance with the DIN 915 standard (equivalent to ISO 4028). The key feature is the dog point, a short, unthreaded cylindrical tip. This tip is designed to fit into a pre-drilled hole or a longitudinal groove on a shaft. This method provides a very secure lock against rotational and axial forces while preventing the damage (marring) to the shaft that can be caused by sharp-pointed set screws.
• Premium Material Options:
  • Stainless Steel (A2/304, A4/316): Ideal for applications requiring superior corrosion resistance, such as in marine, food processing, or chemical environments. These screws have a plain, polished finish, ensuring cleanliness and long-term durability without protective coatings.
  • High-Strength Alloy Steel (45H): Heat-treated to achieve high property classes (8.8, 10.9, 12.9), these screws offer maximum strength and hardness. They are typically finished with a black oxide coating for moderate corrosion resistance and galling prevention.
• Hex Socket Drive: The internal hexagonal drive (Allen drive) allows for high-torque installation using a standard hex key. This is essential for a headless screw, enabling it to be set flush with or recessed below the surface of the assembly for a safe, snag-free profile.

Product Parameters

The technical specifications for our DIN 915 Dog Point Set Screws are detailed below to ensure a perfect fit for your engineering needs.

Product Features

Our DIN 915 dog point set screws are engineered with key features to deliver superior performance in precision applications.

• Precise and Repeatable Positioning: The dog point fits securely into a mating recess, ensuring exact and repeatable alignment of components every time, which is critical for jigs, fixtures, and automated machinery.
• Non-Damaging to Shafts: Because the point seats within a pre-made hole or groove, it locks the component without marring or damaging the shaft surface. This preserves the shaft’s integrity and is ideal for applications requiring periodic adjustments.
• Secure Axial and Rotational Lock: The positive engagement of the dog point provides a strong lock that effectively resists both axial (thrust) and rotational (torque) forces.
• Safe, Headless Design: The ability to install the screw flush with or below the surface creates a clean, compact assembly with no dangerous protrusions, making it perfect for rotating parts.
• High Durability and Reusability: The design minimizes wear on both the screw’s tip and the shaft, allowing for reliable reuse during maintenance or reassembly.

Product Applications

DIN 915 dog point set screws are the preferred fastener for a wide range of precision applications. They are extensively used in power transmission to locate gears, pulleys, and sprockets on a shaft that has a pre-drilled hole or a keyway-like slot. In tool and die manufacturing, they serve as positioning pins or stops in jigs and fixtures. They are critical in automotive transmissions and other precision machinery for locking components onto shafts while allowing for future disassembly without damage. They can also function as a hinge or pivot pin in light-duty applications. The stainless steel variant is particularly suited for marine equipment, food processing machinery, and any assembly exposed to corrosive elements.
