What are the applicable occasions for hexagonal bolts?

External hexagonal bolts/screws are suitable for:

Connection of large equipment;

Suitable for thin-walled parts or situations subject to impact, vibration or alternating loads;

Where the thread is required to be longer;

Mechanical connection with low cost, low power intensity and low precision requirements;

Occasions where space is not considered.

Hexagon socket head bolts/screws are suitable for:

Connection of small devices;

Mechanical connections with high requirements on aesthetics and precision;

Occasions where a heavy head is required;

Narrow assembly situations.

Although there are so many differences between external hexagonal bolts/screws and internal hexagonal bolts/screws, in order to meet more needs, we do not just use a single type of bolts/screws, but need a variety of fasteners and screws. Use together.
