The overheating treatment process of 45 # steel can significantly improve the mechanical properties of steel, increase the strength, toughness and service life of parts, and improve the hardness and wear resistance. Even in challenging environments, they maintain optimal functionality and longevity.
• Instruction: The surface of these thread reducing nuts is smooth, with deep and clear threads that distribute force evenly. To facilitate installation and removal, each thread-reducing nut has a slot at the top for accommodating a flat head screwdriver, making it easier to screw them in.
• Application: Repair insert nuts are essential components in industrial fastening systems and are commonly used in conjunction with screws or bolts. They serve as effective solutions for repairing damaged or incorrectly threaded holes. These versatile repair nuts find extensive application across various manufacturing sectors, including aviation, automotive, electronic communications, computers, lighting fixtures, mechanical equipment, radiators, etc.
• Note: If there is a stripped M12 thread and you wish to continue using an M12 thread, you can use this method to expand the M12 thread to M16, and then recover it back to M12 using the repair nut. By reducing the diameter and utilizing brass material, it will make the M16 thread stronger.
