The main function of fastening tools is to connect, secure, or clamp two or more parts together, ensuring they maintain relative position stability and reliability during use. These tools are widely used in fields such as machinery, construction, automotive, aerospace, and transportation.
Achieve Reliable Connections: Fasteners such as bolts, nuts, screws, and rivets are used to firmly combine parts, bear loads, and resist vibration and impact.
Control Preload and Torque: Tools like torque screwdrivers and hydraulic torque wrenches can precisely set tightening torque to prevent damage from over-tightening or loosening caused by insufficient tightness.
Efficient Assembly and Adjustment: Tools such as hydraulic bolt stretchers and ratcheting fasteners can quickly complete bolt assembly or cargo binding, improving work efficiency.
Adapt to Special Working Conditions: Some tools are specially designed for high-temperature, high-pressure, or confined space environments. For example, hollow hydraulic wrenches are suitable for situations where the screw extends longer.
Ensure Safety: Designs such as self-locking, anti-loosening, and load-limiting (e.g., mechanical self-locking fasteners and clamps) prevent loosening, slipping, or accidental detachment.
Common types of fastening tools include
Manual/Pneumatic/Electric Wrenches and Screwdrivers: Used to tighten threaded fasteners.
Hydraulic Torque/Stretching Tools: Used for high-precision fastening of large bolts.
Rivet Guns: Achieve one-sided riveting, suitable for thin plates or enclosed structures.
Nail Guns: Used for quick fastening on substrates such as concrete and steel.
Fasteners/Binders: Mainly used for binding and securing cargo during transportation.
