Different Types of Direct Assembly Screws

At Bossard, we distinguish between different types of screws for direct assembly:

  • Self-drilling screws require no pre-drilling, which makes them ideal for quick and efficient installation.
  • Thread-cutting screws create a mating thread in hard materials while still requiring only a low installation torque.
  • Thread-forming screws are optimal for high clamp load and providing vibration resistance.
  • Multifunctional screws with integrated washers provide increased security while enabling you to reduce C-parts.

Make your installation process faster, safer, and more durable with versatile and economical products from our many expert partners. We offer a broad range of direct assembly solutions, including the following:
