Thank you for viewing. Price reduced!! Insert nuts can be removed. (Non-sert) Delta PT 2x6 Trivalent chromate Approximately 3800 pieces. Anonymous delivery, free shipping. Thank you. ★B+DELTA PTscrew Delta PT is a tapping screw for resin, but it has the idea of holding the fastening with axial force like a bolt, and high fastening force can be obtained. It also has good repeated use, and can be used for fastening parts that were impossible with conventional tapping screws. By utilizing the high axial force, it is also possible to downsize the screw. Main applications For fastening with the bolt concept that you want to hold with high axial force. When removing the housing, etc., and repeating fastening many times. For automotive parts such as inlet manifolds. Product features Screw thread shape: Excellent repeated use The small volume of the female thread formed by the sharp-angled screw thread of the composite angle reduces the screwing torque. In addition, the resin flows smoothly into the valley of the screw to form the female thread, suppressing heat generation and minimizing resin creep. Repeated use is realized by the beautifully finished female thread. Screw shape Lead angle and pitch It has a lead angle and pitch that can obtain a large contact area for the same engagement. This allows for a large fastening force (axial force) to be obtained and maintained even at low surface pressure. Screw thread cross-section and stress distribution The screw cross-section is circular, and the contact area with the mating material is large. In addition, the stress is also distributed, making it less likely for the boss to crack. Heat treatment and strength Tempering is performed to minimize the risk of brittle fracture. The strength class is 10.9.
