EJOT Micro Screws – Maximum performance in minimal installation space
Jun 6, 2023
Whether it is consumer electronics, the automotive industry or medical engineering – application areas for connections in small installation spaces are increasing steadily. The related, particularly high demands on the use of fastening elements rise even more, the smaller the fastening solution is dimensioned. Under these special circumstances, EJOT offers excellent fastening technology know-how.
Reaching this high level of requirements concerning the design and implementation of innovative fastening solutions in the "micro area" is daily business in many projects at the fastening technology expert EJOT. Reliability and cost-efficiency thanks to the self-tapping feature of the fasteners are important and at the same time self-evident parameters in the design.
It is now possible to produce a DELTA PT® screw for direct assembly in thermoplastics, designed as a micro screw, with a nominal diameter of 1 mm. These micro screws offer all advantages of the larger dimensions. The possible spectrum ranges from manual to automated assembly which is already used for many applications. As an example, the assembly of lidar or radar sensors, camera systems, smartphones, printed circuit boards or small medical devices shall be mentioned here.
By using self-tapping screws, a high degree of mechanical strength of the assembly can be reached also in small installation spaces. The maximum strength is realized with a zero-tolerance thread. As is known, there is always a defined tolerance in the thread pairing for metric screw joints. The smaller the connection is designed, the more important becomes the advantage of a tight-fitting connection with self-tapping screws. Therefore, a long-lasting and very reliable connection is guaranteed for EJOT micro screws as well.
The self-tapping feature of these micro screws also saves the additional work step of thread cutting in the component. Furthermore, the very high tool wear, which occurs with metric screws due to the necessary step of thread cutting, is prevented. Thus, significant cost saving potentials can also be realized in the design of screw connections by using EJOT micro screws.
