GVN Güven Civata is a family company that has been manufacturing bolts in Istanbul since 1957. Today it supplies furniture manufacturers with everything from fasteners to mechanisms, and its story begins with a lathe operator's journey.
From Skopje to Istanbul with a lathe
Founder Selman Şengül began working as a lathe operator at a chrome mine in Raduša near Skopje in 1938. In 1952 he moved to Istanbul together with his lathe.
1955–1957: Şengül Cıvata
In 1955 the brothers Selman, Mustafa and Zeki Şengül founded Şengül Cıvata, and in 1957 they began producing bolts by cold forming, where steel wire is pressed between dies without heating to form the head and shank, preserving the grain flow of the material.
1975: Güven Cıvata
With the second generation, Erol Şengül, the company became Güven Cıvata. In 1992 it moved to Bayrampaşa, Istanbul, and expanded its capacity.
2006 onwards
The third generation joined in 2006 and focused the company on the furniture industry, adding minifix, mechanisms, upholstery supplies and furniture legs to frame bolts, socket bolts and studs. A retail store opened in Bayrampaşa in 2018, and the main factory moved to Beylikdüzü, Istanbul in 2020.
