Is there any head limit for long black screws?

Those who are familiar with screws know that there are many head types of screws, such as pan head, round head, truss head, countersunk head, ultra low profile head, cylinder head, PF head, button head, and so on. So when the length of the screw becomes much longer, is there any limit to the shape of the head of the long black screws?

Among the long black screws we often see, the head shape we often see is the external hexagon, and the hexagon head, cap head. Is there really a limit to the rarity of other hairstyles? Not really. Even if the length of the screw becomes longer, there is no limit to the shape of the head. As long as you want what type of head, as long as the wire forming a reasonable coefficient can be produced.

Long black screws with other head shapes are relatively rare, mainly because the customer’s demand is more for the hexagon head and the cap head hexagon socket, or the customer may not know that such a long screw can also make other head shapes. The specific head type is determined by the customer, not by the manufacturer.
