About This Product

■No need to form a female thread using a tap

When using machine screws, you need to drill a pilot hole with a drill or punch, then tap it to form a female thread, but if you use deltite screws, there is no need to use a tap to form the 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.

■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 machine screws, but in order to make tightening work easier, various self-tapping screws have a large pilot hole diameter, which reduces the contact area with the mating thread, making them more likely to loosen. Masu. In addition, 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 part to form a female thread, which reduces the generation of cutting dust. You can. Compatible with machine screws. (Deltaito 3) The outer diameter of Deltaito 3 is slightly larger than the outer diameter of the machine screw, so even if you lose the Deltaito screw, it is designed so that you can use the machine screw. I'm here.

■Structure of deltite screw

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.
