However, the production and manufacturing areas of Decal bolts are mainly concentrated in coastal cities.

This undoubtedly creates the inherent standard for companies in coastal cities to produce and manufacture pasted bolts.

Generally, flat round head is used for core riveting, and countersunk head is suitable for riveting places where the surface must be smooth.
