Selection factors of fasteners
Materials and Strength: Select appropriate materials and strength grades based on the working environment and load-bearing requirements.
Size and profile: The size and profile of fasteners should meet actual needs, usually using the national standard fastener size.
Compatibility with connectors: The aperture size and threads of the connectors should match the fasteners, otherwise it may cause the connectors to loosen or be damaged.
Environmental conditions: Different environmental conditions require different materials, such as using stainless steel fasteners for environments that are humid and susceptible to chemical corrosion.
The function of fasteners: Select appropriate locking fasteners or connecting fasteners based on their function during transportation or installation.
Usage conditions: Consider the effectiveness of fasteners, fatigue test data, tensile strength, torsional strength, and other data.
