The Taptite screw forms its own threads by way of the trilobular cross-section. The threads are formed by plastic forming witch provides a number of advantages. Here are just some of the more important.

• Faster and simpler assembly as no washers or nuts is needed.
• Stronger threads thank to plastic forming in stead of cutting.
• Completely burr-free threading, no burrs in blind holes or in electrical installations to be removed after threading.
• Threading costs are eliminated. The Taptite screw is driven direct into a drilled or cast hole.
• Cleaning cost after painting is eliminated. The Taptite screw can easily be screwed in even if there is paint residue in the hole.
• No locking elements required, the Taptite screw is an excellent locking-screw itself.
• Quite simple “lower in place cost”.
