Learn more about Klarna
Description
The Carmex Threading Tap is a Forming Tap (Roll) designed for UNF applications, delivering consistent thread formation in production settings. Built with a powder metal body, it’s engineered for durability and long tool life in demanding materials.
- Tap Type: Forming Tap (Roll) — creates threads by plastic deformation, delivering chip-free threading and a smooth thread finish.
- Thread Standard: UNF (Unified National Fine) — specifically sized for precise UNF threading.
- Size: 7/16" diameter, 20 TPI (7/16-20 UNF) — a common UNF specification for many assemblies.
- Material: Powder metal construction — offers durability and cost-effective performance for tough materials and high-speed use.
- Geometry: UNF Supercut geometry — designed to promote clean forming and longer tool life.
- Applications: Suitable for high-speed threading in ductile materials and production environments, with the ability to form threads in through or blind holes.
- Waste Reduction: Forming taps displace material rather than cut, reducing waste and improving efficiency in manufacturing runs.
Using this forming tap delivers consistent thread quality across production runs, minimizes scrap, and supports faster cycle times thanks to chip-free forming and high-speed capability. The powder metal construction provides robust performance in challenging materials, while the Supercut geometry helps ensure a smooth, reliable thread finish on UNF fasteners. This makes it a dependable choice for manufacturing, automotive, and other precision-treated assemblies that rely on durable UNF threading.
