rundhuvud

Rundhuvud is a Swedish noun meaning round head. It is used as a descriptive term to indicate that an object has a rounded or domed head. The word is formed from rund (round) and huvud (head) and appears in technical writing as well as everyday language. Its exact scope depends on context, since it is not a fixed, standalone technical name but a descriptive label.

In hardware and construction, rundhuvud is commonly used to distinguish fasteners and components with a convex top from those with flat, countersunk, or other head shapes. Round-headed fasteners are often chosen when a visible, non-recessed head is desired or when ease of driving and a smooth finish are priorities. They are typical for nails, rivets, and screws that are finished with a rounded profile.

Linguistically, rundhuvud can appear as a standalone noun or as part of compound nouns naming specific items, such as rundhuvudspik (round-headed nail) or other hardware terms where the head shape is a characteristic feature. The term is broadly understood in Swedish technical literature, manuals, and retail descriptions, but it does not correspond to a single standardized product number; its precise meaning is defined by the accompanying noun.

Overall, rundhuvud serves as a practical descriptor for objects with rounded heads across several domains, especially in hardware terminology. See also screw head shapes, nail heads, and hardware terminology for related concepts.
