  • What is a screw

    Screw is a combination of simple machines—it is, in essence, an inclined plane wrapped around a central shaft, but the inclined plane (thread) also comes to a sharp edge around the outside, which acts a wedge as it pushes into the fastened material, and the shaft and helix also form a wedge in the form of the point. Some screw threads are designed to mate with a complementary thread, known as a female thread (internal thread), often in the form of a nut, or object that has the internal thread formed into it. Other screw threads are designed to cut a helical groove in a softer material as the screw is inserted. The most common uses of screws are to hold objects together and to position objects.

  • Fastener surface treatment process

    For the surface treatment of fasteners, people generally pay attention to aesthetics and anti-corrosion, but the main function of fasteners is to fasten parts, and surface treatment also has a great influence on the fastening performance of fasteners, so choose the surface When handling, the factor of fastening performance should also be considered, that is, the consistency of installation torque-pre-tightening force.

  • The development status of titanium alloy for aviation fastener is introduced

    Titanium alloy fasteners are widely used in aerospace because of their low density, high specific strength and corrosion resistance. The development status of titanium alloy materials for aviation fasteners is reviewed. Combined with the development of titanium alloy for fasteners, the application status of titanium alloy for fasteners at home and abroad is introduced, and the performance characteristics of titanium alloy materials for fasteners are compared and analyzed. At the same time, combined with the requirements of advanced aircraft for high-performance fasteners, several high-strength and toughness titanium alloy materials for fasteners and their fastener processing technology are introduced.
