Screw Locking Fastener

Screw Tightening Caliper Accessories

Screw locking and fastening technologies are critical in mechanical assembly to prevent threaded connections from loosening due to vibration, impact, or temperature changes. These technologies are primarily categorized into mechanical locking (e.g., washers, lock nuts), chemical locking (thread adhesives), and metallurgical locking (e.g., spot welding). Modern screw locking solutions must balance reliability against loosening, ease of disassembly, and environmental adaptability, making them essential in demanding industries such as aerospace, automotive manufacturing, and precision instruments.
