About This Product
■No need to form female threads using taps. Significant cost reductions can be achieved.
When using machine screws, you need to drill a pilot hole with a drill or punch and then use a tap to form a female thread, but if you use a deltite screw, there is no need to use a tap to create a female thread. In other words, the deltite itself plays the role of a tap and is screwed in and tightened while forming a female thread. Therefore, there are no tap costs, resulting in a significant cost reduction.
■Low screwing torque and excellent workability.
Compared to various types of self-tapping screws, deltite screws have a spoon-shaped tip that gradually forms a female thread, so the screwing torque is extremely low, helping to improve work efficiency and reduce operator fatigue.
■High holding power and does not loosen even under vibrations and shocks.
Of course, they have a higher holding power than small screws, but in order to make tightening work easier, various types of self-tapping screws have a large pilot hole diameter, which reduces the contact area with the mating thread, making them more likely to loosen. It will be. Additionally, there is a possibility that the female thread may be damaged, but since the deltite thread plastically forms the mating thread, the deltite thread and the female thread are in perfect contact with each other, which is highly effective in preventing loosening.
■Less cutting powder.
Tapping screws with indexed tips generate cutting dust when screwed in, so they may not be usable depending on the product, but deltite screws plastically deform the mating material to form a female thread, which reduces the generation of cutting dust. You can. Compatible with machine screws. (Batani of Deltight 3) The outside diameter of Deltight 3 is slightly larger than the outside diameter of the machine screw, so even if you lose the Deltight screw, it is designed so that you can use the machine screw. I'm here.
■Deltite screw structure
Deltite screws are screws that have a guide taper at the tip of the thread, and several spoon-shaped recesses at three locations on the circumference to form a female thread through plastic deformation. In addition, it is divided into Deltaito 2 and Deltaito 3 depending on the shape of the threaded part. The threaded part of Deltaito 2 has the same outer diameter and pitch as the two types of self-tapping screws. Deltaito 3 is slightly larger than the outer diameter of a machine screw (JIS class 2), and the pitch is the same as a machine screw. In addition, the material is low carbon steel that has been gas carburized and tempered to fully utilize its characteristics as a self-tapping screw.
