Definition of Type 17 Screws
Type 17 screws have a distinct thread profile and a built-in drill point at the tip. They combine a coarse thread with a sharp flute that cuts into wood and plastics, eliminating the need for pilot holes. You install them with a standard Phillips or Pozidriv driver. Because the point clears material as it advances, you reduce splitting and speed up assembly.
You find Type 17 screws in wood framing, decking, and joinery. They work best in soft and hardwood. Engineers and buyers choose them when they need faster installation, consistent torque, and reliable holding power for strong, durable connections.
Why It Matters for Screws and Fasteners
When you use Type 17 screws, you save time on pilot drilling. This speeds up workflows on job sites. You cut labour costs and reduce assembly errors.
Their self-drilling tip and reliable thread pull you more consistent results. This lowers rework and warranty claims. You improve product quality and customer satisfaction.
FAQ
What distinguishes Type 17 screws from other wood screws?
Type 17 screws feature an integrated drill point and coarse threads. This self-drilling tip cuts its own hole and clears chips, unlike standard wood screws that need a pilot hole first.
What driver type fits Type 17 screws?
You use a Phillips or Pozidriv driver, matching the screw’s head recess. Pozidriv heads offer extra torque resistance and reduce cam-out during installation.
How do Type 17 screws reduce splitting?
The sharp flute clears material as the screw advances. This lowers pressure on surrounding fibers, preventing cracks in wood.
