Titanium alloy screws, due to their lightweight, high corrosion resistance and excellent specific strength, have become the preferred fasteners in fields such as aerospace, automotive modification, and marine engineering. However, due to their material properties, the installation operation differs significantly from that of ordinary steel or stainless steel screws. Improper operation may lead to thread slippage, deformation or even fracture. Therefore, mastering the correct installation techniques is particularly important.

Before installation, it is necessary to complete the necessary preparatory work. Firstly, check the compatibility between the screws and the screw holes. Ensure that the specifications and thread types are consistent. Titanium alloy screws have a low elastic modulus, and mismatched screw holes may cause stress concentration. Secondly, clean the oil stains, rust, and impurities on the surfaces of the screws and screw holes. Impurities will increase the friction during installation and may cause damage to the threads. You can use anhydrous ethanol to wipe and keep the surfaces clean. At the same time, it is recommended to prepare a special anti-adhesion agent. When titanium alloy comes into contact with metals such as steel and aluminum, it is prone to adhesion and sticking at high temperatures or under high pressure. Applying an anti-adhesion agent can effectively prevent this problem.

During the installation process, torque control is crucial. Titanium alloy screws must not be over-tightened as their plastic deformation capacity is different from that of steel. Over-tightening operations will directly lead to thread slippage, screw deformation, and even micro cracks that affect strength. It is necessary to strictly follow the torque standards marked on the product and operate using a torque wrench. Adhere to the principle of "gradually increasing force and tightening in stages", and never operate蛮力based on your sense of touch. Additionally， during installation， ensure that the screws are perpendicular to the working surface. Slightly skewed tightening will cause uneven force distribution， which is very likely to result in screw breakage. In multi-screw tightening scenarios， use the diagonal tightening method to ensure uniform force distribution.

Installation and subsequent maintenance are also crucial. It is strictly prohibited to strike titanium alloy screws with hard objects. Their impact resistance is weaker than that of steel, and striking them may cause hidden cracks, reducing their service life. In outdoor, chemical, and other corrosive environments, after installation, regular inspections of the screw condition can be conducted. If the surface shows wear, timely surface protection treatment should be carried out. If disassembly is necessary, a torque wrench should be used, combined with anti-biting agent assistance, to avoid hard removal and prevent damage to the threads.
The core of installing titanium alloy screws lies in conforming to their material characteristics, doing a good job in details control, and following standardized operation procedures, so as to fully exert their performance advantages and ensure the stability and durability of the fastening connection.
