Methods To Protect Stainless Steel Bolts From Corrosion And Effectively Loosen Rusted Anti-theft Screws

Using stainless steel material: Choose 304 or 316 stainless steel bolts, which have good corrosion resistance and can withstand corrosion in most environments.
Surface treatment: Surface treatment of bolts, such as galvanizing, chrome plating, or coating with anti-corrosion coatings, to increase their corrosion resistance.
Use anti-corrosion lubricant: Apply a layer of anti-corrosion lubricant before installing bolts to reduce corrosion when in contact with other metals.
Method of unscrewing rusty anti-theft screws:
Use screw loosening agent: Spray or apply screw loosening agent on rusted screws to allow it to penetrate into the threads and help loosen the rusted screws.
Use appropriate tools: Select the correct size wrench, wrench head, or torque tool to ensure the screw is securely locked, and rotate counterclockwise to loosen the screw.
Heating screws: Use a flame or hot air gun to heat the area near the screw head and apply the thermal expansion effect to the screw, which helps loosen corroded screws.
It should be noted that before performing any operation, ensure that appropriate safety measures are taken and choose the appropriate method based on the specific situation. If unsure how to handle it, it is recommended to seek professional help or consultation.
